Pairwise statistics (e.g., "robust_slope") are now
supported by polarMap(). (#72)
The polarMap() family has gained the
progress argument, allowing users to switch the progress
bar on and off.
trajMapStatic() has gained the size and
linewidth arguments, which directly map onto the arguments
in ggplot2::geom_point() and
ggplot2::geom_path(), respectively. These can either be a
column of the data (like colour), or can be an absolute
value (e.g., 2L). Note that, by default,
linewidth takes the value of size, but both
can be set independently.
Vectors greater than length 1 passed to popup in the
polarMap() argument will no longer error when
type = NULL.
... will successfully pass to
openair::cutData() in the polarMap() and
trajMap() families of functions.
The default diffMap() colour scale will no longer
appear inverted compared to openair::polarDiff().
Fixed an issue in which quickTextHTML() would
incorrectly format non breaking spaces when doing, e.g.,
quickTextHTML("ug/m3").
The order in which trajMapStatic() draws points and
paths has been tweaked, which should ensure that markers are drawn on
top of their respective path, rather than on top of all paths.
buildPopup() will now work correctly if no
type is provided.
BREAKING: The polarMapStatic() family is now powered
by {ggspatial} rather than {ggmap} as it does
not require an API key. This means the ggmap argument has
been removed and the provider argument has been added.
Other benefits of this switch include a greater number of available base
maps (see: rosm::osm.types()) and the ability to simply
change the extent of the map axes using
ggplot2::coord_sf(). (#52)
BREAKING: The control and facet
arguments have been deprecated in favour of type in all
functions. These arguments will eventually be removed, but as of this
version of {openairmaps} users will be warned away from
their use. This brings {openairmaps} in-line with the
{openair} package.
BREAKING: The names and cols arguments
of buildPopup() have been coalesced into a single
columns argument for less verbose function usage.
BREAKING: The collapse.control argument has been
renamed to control.collapsed and the
draw.legend argument to legend. This is to
allow these options to sit more nicely with their new argument family
members - legend.title, legend.title.autotext,
legend.position, and so on.
The polarMapStatic() family of functions have been
combined with the polarMap() family, with static maps
available to be accessed using the static argument. (#59)
The polarMapStatic() family are therefore deprecated, and
will later be removed from {openairmaps}. The justification
for this is as follows:
The combined functions allows for a more simple, consistent API
for users (e.g., avoiding needing to switch between facet
and control).
The use of the static argument allows for simple
switching between dynamic and static maps. For example, a researcher may
wish to use the dynamic maps for data exploration, but then switch to a
static map for placement into a PDF report.
Recent developments have meant that the arguments and capability
of these functions have started to align regardless (e.g.,
provider, crs).
Combining these functions has reduced repetition in the source
code of {openairmaps}, reducing the likelihood of
oversights and bugs, and allowing for more rapid development.
The crs argument has been added to the
polarMap() and polarMapStatic() families and
to searchNetwork(). This argument allows for users to
specify that their data is using an alternative coordinate system to the
standard longitude/latitude (e.g., the British National Grid CRS).
Alternate CRS will be re-projected to longitude/latitude for plotting as
this is expected by {leaflet} / {ggspatial}.
(#56)
Users now have greater control over the positions of legends and
layer control menus, and the titles of legends, throughout
{openairmaps} functions, including the
polarMap() family, trajMap() family, and
networkMap().
Popups for the dynamic polarMap() family will now be
near the top of the plot rather than the centre. This will obscure less
of the plot itself while the marker is visible. (#55)
quickTextHTML()’s lookup table has gained new
pollutants and units, and ignores the input case of text
more consistently.
Two examples of the use of {openairmaps} with
{shiny} have been added to the package. Run
shiny::runExample(package = "openairmaps") to view these.
(#60)
Legends drawn by the polarMapStatic() function
should now render using more recent versions of
{ggplot2}.
The addTrajPaths() layerId argument is
now implemented in a sensible way to ensure each geometry has a unique
layerId and can therefore be interacted with in a
{shiny} context.
layerId is now the base on which the actual layerId is
built, with each real layerId in the form BASE-LN-PN where LN is the
line number and PN is the point number. For example, if
layerId = "traj", the first point of the first line has the
ID "traj-1-1", the second point of the first line has ID
"traj-1-2", the first point of the second line has ID
"traj-2-1", and so on.“illegal” file path characters can now be used in the columns
provided to the type argument of the
polarMap() family. Most relevant to most users is that this
will allow them to provide their own custom HTML tags - e.g., for
formatting superscripts, subscripts, and so on. (#63)
The colours in the legend of networkMap() now better
align with the actual colours of the markers, and the layer control menu
when control = "variable" is now presented in a nicer order
with clearer labels.
This is a minor release of {openairmaps}, released
mainly to fix an issue with {ggmap} but also adding some
new functionality for polar marker maps.
BREAKING: The arguments of addPolarMarkers() have
been rejigged to move “data” after “pollutant”, owing to the new use of
leaflet::getMapData(). (#45)
BREAKING: The default arguments of some
polarMap()-family functions have changed from, e.g.,
NULL to "free" or "fixed".
(#34)
BREAKING: Due to changes in {ggmap}, all static
polar plotting functions now require users to provide their own
ggmap object. The zoom argument has also been
removed. This is specifically related to the partnership of Stamen and
Stadia which has put the stamen tiles behind an API. See https://maps.stamen.com/stadia-partnership/ and https://github.com/dkahle/ggmap/issues/353 for more
information. (#52)
Several “limit” arguments can now take one of three options: “fixed” (which forces all markers to share scales), “free” (which allows them to use different scales), or a numeric vector to define the scales. (#34) These arguments and their defaults include:
polarMap(): upper (fixed);
limits (free)annulusMap(): limits (free)freqMap(): breaks (free)percentileMap(): intervals (fixed)Added searchNetwork(), which allows users to find
local air quality monitoring sites by specifying a target latitude and
longitude. Function arguments allow the site metadata to be subset (for
example, by site type, pollutants measured, or distance from the
target).
Added convertPostcode(), which converts a valid UK
postcode to a latitude/longitude pair. This is intended to be used with
searchNetwork().
The “data” argument of addPolarMarkers() and
addTrajPaths() and both the “before” and “after” arguments
of addPolarDiffMarkers() now default to
leaflet::getMapData(map). This makes their use less verbose
when creating multiple polar plots with the same underlying data, which
will likely be a common use-case. (#45)
networkMap() popups now contain links to the
associated network websites. For example, the popup for London
Marylebone Road in networkMap("aurn") now contains a link
to https://uk-air.defra.gov.uk/networks/site-info?site_id=MY1.
All networks are supported with the exception of “europe”.
(#39)
addPolarMarkers() and
addPolarDiffMarkers() now have all of the “options”
arguments of leaflet::addMarkers(). This means that, for
example, polar markers can be clustered (https://leafletjs.com/reference.html#marker).
(#38)
The polarMap() family and networkMap()
provider argument can now take a named vector. The names
will be used in the layer control menu, if
length(provider) > 1. (#42)
This is a minor release adding a range of quality of life features, adding two new experimental functions, and fixing a few bugs.
trajMapStatic() and
trajLevelMapStatic() have been added as two new
experimental functions to provide {ggplot2}
equivalents of openair::trajPlot() and
openair::trajLevel(). (#28)
{ggplot2}
incarnation of the trajectory plotting functions, but whether they will
sit in {openair}, {ggopenair} or
{openairmaps} and what they will be named is not
clear.The control and facet arguments of all
polar marker mapping functions (static and interactive) and trajectory
mapping functions are now passed to
openair::cutData().
The popup argument of all interactive polar marker
mapping functions can now take a vector of column names. If more than
one column is provided, it is automatically passed to
buildPopup() using its default values.
trajLevelMap() now has the control
argument, which maps directly onto the type argument of
openair::trajLevel(). Like other control
arguments elsewhere in {openairmaps}, this creates a “layer
control” menu.
networkMap() now uses different coloured markers for
different networks. If more than one network is specified, and
draw.legend is set to TRUE, a legend will also
be drawn for quick identification of different data sources.
(#30)
Deprecations are now managed by the {lifecycle}
package. This currently only applies to the type
argument.
Fixed issues where multiple addPolarMarkers()
chained together would all show the same plot.
Fixed issue where ... and pollutant
weren’t being passed to addPolarMarkers(). (#27)
Fixed issue in trajMap() caused by recent updates to
{dplyr} and {forcats}.
Fixed issue where polarMapStatic() and others would
turn factor facet levels into characters.
cutData(), will now be honoured by the
facet argument. (#31)Fixed issue where polarMapStatic() and others would
error when trying to draw a legend.
This is a minor release containing several important new features
that expand the scope of the package. This also comes with several minor
breaking changes to improve consistency within
{openairmaps} and with {openair}.
BREAKING: The fig.width, fig.height,
iconHeight and iconWidth arguments have been
replaced with d.fig and d.icon. There are two
main justifications behind this:
This ensures consistency across all of
{openairmaps}, making it easier to switch between the
static and HTML map types.
Polar markers are almost always going to be circular (i.e., width
= height) so having one argument will streamline things. If users wish
to have non-circular markers, a vector of length two in the form
c(width, height) will provide the same
functionality.
BREAKING: The arguments in addPolarMarkers() have
been put in a more sensible order, leading with data,
pollutant and fun.
BREAKING: The date argument from
networkMap() has been replaced by year.
(#26)
Added “static” equivalents of all of the polar marker maps
written in {ggplot2}. While interactive HTML maps are
preferred, the static equivalents may be more appropriate for, e.g.,
academic publications. (#19)
The {ggplot2} functions can be identified by
“Static” being appended to the function name. For example,
polarMap() is the {leaflet} polar plot map,
whereas polarMapStatic() is the {ggplot2}
equivalent.
Currently, “static” versions of the trajectory maps are served by
openair::trajPlot() and openair::trajLevel(),
but there may be space in future to have ggmap equivalents
of these in openairmaps.
Added diffMap() and diffMapStatic()
which are to openair::polarDiff() what
polarMap() and polarMapStatic() are to
openair::polarPlot() (#17). Also added
addPolarDiffMarkers(), which is the equivalent of
addPolarMarkers(). (#25)
Added alpha as an argument to all of the directional
analysis polar mapping functions, not just polarMap().
(#14)
Fixed alpha to work on both Windows and MacOS by
forcing the use of the “cairo” device to save plots. (#14)
Polar marker maps and addPolarMarkers() now show a
progress bar when creating the markers takes more than a few seconds
(most commonly in polarMap() and annulusMap(),
particularly with multiple pollutants/control groups).
networkMap() can now pass the new year
option to importMeta().
This is a patch release primarily to fix a few bugs in
{openairmaps}, and implement a new default colour scheme
after a recent {openair} update.
Fixed issue with polar marker maps (e.g.,
polarMap()) and the generic addPolarMarkers()
function where lat/lon info in the Southern Hemisphere would misalign
markers. Hat tip to Deanna Tuxford and James for noticing this issue.
(#18)
Fixed an issue with networkMap() where
control = "variable" would fail to show all
pollutants.
This is a minor release, mainly focusing on enhancing the ability for polar markers to have shared colour scales, but also incorporating new features for network visualisation.
All directional analysis maps can now have their limits provided
(can be “limits”, “breaks”, “percentiles”, etc., depending on function).
This was always possible through ..., but it is now
explicitly listed as an option. (#12)
If limits are defined in a directional analysis function, a
shared legend will now be drawn at the top-right of the map. This
functionality can be disabled by setting draw.legend to
FALSE. (#12)
Added the buildPopup() function, which allows users
to easily construct HTML popups for use with the “popup” argument of
directional analysis maps (or leaflet maps more
widely).
The default options for fig.width and fig.height are now
3.5 rather than 4. This appears to remove some
visual artefacts and makes the axis labels more legible.
networkMap() now supports multiple sources. For
example, using source = c("aurn", "saqn") will show both
the AURN and SAQN on one map. This may be useful if users are interested
in air quality in a specific region of the UK (e.g., users may wish to
locate AURN, AQE and locally managed sites near to a given
urban centre). (#16)
networkMap() now supports
source = "local".
Multiple basemap providers can now be used with
networkMap().
networkMap(), trajMap() and all polar
directional analysis maps have gained the collapse.control
argument, which controls whether the control menu starts collapsed or
not. It defaults to FALSE, which means the control menu is
not collapsed.
All documentation has been improved; function parameters are more
consistent between functions and arguments passed to
openair via ... are now explicitly
listed.
polarMap() as it only ever worked for
polarMap().This is a patch release designed to fix a major bug in v0.5.0.
This is a minor release centred around the addition of the
control argument, which allows for arbitrary columns to be
used in “layer control” menus.
All functions now use latitude and longitude to distinguish
between site types. Therefore, “type” is now deprecated. Maps using the
old system will still render, but popups will not be displayed. For most
users, to restore previous site labels simply rewrite
type = "site" as popup = "site".
(#10)
The default values for “pollutant” have all been removed. Any
users relying on this default should update their code to explicitly
state pollutant = "nox".
All functions now possess the “control” argument, which allows
users to create a “layer control” menu with any arbitrary column.
Appropriate columns may be those produced using
openair::cutData(), openair::splitByDate(), or
a user-defined
dplyr::case_when()/dplyr::if_else() column
transformation. (#9)
All functions now possess the “popup” and “label” arguments, which control pop-up and hover-over labels, respectively. This allows users to define any popup or label column, even non-unique ones. For example, multiple sites can be labelled with identical site types. (#10)
All functions now try to guess the latitude/longitude column if
not provided, similar to {leaflet}. (#10)
Updated many error messages and warnings to use
{cli} and be broadly more descriptive.
trajMap() can now be coloured by date.
Fixed issue with trajMap() that would cause
user-defined colours not to work.
This is a patch release adding a small number of refinements.
polar_data column names changed from “latitude” to
“longitude” to “lat” and “lon” to reflect the defaults of the
polarMap() family.
trajMap() and trajLevelMap() now use
the argument names “latitude” and “longitude” to match those of the
polarMap() family.
trajLevelMap() now contains the lat.inc
and lon.inc arguments.This is a patch release to fix a bug with
trajLevelMap().
trajLevelMap() now works where
statistic = "frequency" without a “pollutant”.This is the first CRAN release of {openairmaps}.
There are currently three streams of functionality in
openairmaps:
networkMap() visualises any of the
openair::importMeta() networks.
polarMap() and family allow for any of the
openair directional analysis plots to be used as leaflet
markers.
trajMap() and family are leaflet equivalents to
openair::trajPlot() and
openair::trajMap().
There are two main classes of functions:
*Map() functions are easy-to-use functions which
create leaflet maps from the ground-up. These are the most similar to
openair functions.
add*() functions are more flexible and allow users
to add layers to existing leaflet maps. These are designed to be similar
to the leaflet “add” functions like
addMarkers().
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
