ltertools
- Tools Developed by the Long Term Ecological Research Community
The goal of ltertools is to centralize the R functions
created by members of the Long Term Ecological Research (LTER)
community. Many of these functions likely have broad relevance that
expands beyond the context of their creation and this package is an
attempt to share those tools and limit the amount of “re-inventing the
wheel” that we each do in our own silos.
The conceptual theme of functions in ltertools is
necessarily broad given the scope of the community we aim to serve. That
said, the identity of this package will likely become more clear as we
accrue contributed functions. In the meantime, please do not hesitate to
add or request a function for fear that it doesn’t “fit” this package.
That may eventually become a concern but at this stage we are aiming to
house all extant functions regardless of their relatedness to
one another.
You can install the development version of ltertools
from GitHub with:
# install.packages("devtools")
devtools::install_github("lter/ltertools")As functions are added to the package they will be briefly summarized below and attributed to their author(s)
make_json – creates a JSON containing
name/value pairs from a named vector. If desired, can also add the
created JSON’s filename to the .gitignore (if one exists in the working
directory)begin_key – creates the first two
columns of a ‘column key’ and–if the optional guess_tidy
argument is set to TRUE–“guesses” at what the tidy names
‘should be’
harmonize – performs column
key-based harmonization. We strongly recommend using the
begin_key to start the creation of a column key to make
sure the formatting requirements of this function are met
read – Reads in all files of
specified types in a particular folder and stores them as elements in a
list. List element names are the respective file names. Currently
supports CSV, TXT, XLS, and XLSX file formats
solar_day_info – Identify sunrise,
sunset, solar noon, and day length for all dates within a user-specified
range at particular coordinates. Function concept contributed by Miguel C. Leon
cv – Calculate coefficient of
variation (CV) from a vector of numbers
convert_temp – Convert temperature
values from one set of units to another
site_timeline – Create a timeline of
sites that meet user-specified site code and/or habitat criteria. Uses
built in lter_sites data object that includes much useful
site informationSee CONTRIBUTING.md for specifics but at a glance:
To contribute one of your functions in exchange for authorship credit: open a GitHub issue
To suggest minor fixes or point out bugs: open a GitHub issue
To implement major / structural changes: fork the repository, add
your content to the dev folder, and open a pull request
when you are finished
ltertools will maintain a consistent “feel” and style of
functions but we (the maintainers) are happy to perform these edits on
your behalf. If you’d like to take care of this yourself (completely
optional!) you are welcome to do so. Please see
CONTRIBUTING.md for a specific style guide.
If you would like to contribute a function that is similar to a
function that already exists in ltertools please do not
hesitate! In the event that this happens, the following steps will be
followed:
The functions will be combined to preserve the earlier function’s elements while expanding to include the maximum number of novel features (i.e., arguments / options)
Both function authors will be credited in the combined function’s description and in this README (see above)
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.
