complement.nb, diffnb,
dnearneigh, droplinks, edit.nb,

replace rgrass7 with rgrass in
vignette
fix #133 (edit.nb affected by not attaching
sp)
mat2listw() warning if no style=
argument given, or if M" is given
https://github.com/r-spatial/spatialreg/issues/24,
https://github.com/r-spatial/spatialreg/issues/23.
remaining users of run_perm() -
localC(), localmoran_bv() and
local_joincount_uni() get no_repeat_in_row=
arguments.
Address 2) in #124; localG_perm() and
localmoran_perm() get no_repeat_in_row=
arguments to use conditional permutation without replacement by sample
vectors; the default implementation uses sampling with replacement,
which is acceptable across simulation draws, but arguably less
acceptable within draws. Feedback would be valued.
Address 1) in #124; localG_perm() and
localG() now return the same analytical standard deviates.
The standard deviates from the simulated distributions are now returned
in attr(., "internals")[,"StdDev.Gi"] from
localG_perm(), as are p-values, etc.
move sp from Depends to Imports, to reduce the visual impression that sp objects are required for spdep; sf objects are now preferred, but sp objects can be used as before, although users may need to attach sp expliciitly.
fix #121 and #123; correcting returned values for
localG_perm() when estimating the G-star measure (fix self
x values and weights)
address #120, moving documentation of listw2U() from
?lm.morantest to ?nb2listw

updating coercion for Matrix 1.4-2
fix ncpus issue in dontrun examples

Revise and add documentation for object returned by
localC_perm() #68 #72 #73 #74 #75 #76
localmoran.sad(), localmoran.exact()
and localmoran.exact.alt() will now use multiple compute
nodes if needed; if Omega is used, multiple cores may need
more memory #77
For s2 > 1.0.7, use indexed distances in
dnearneigh()
https://github.com/r-spatial/s2/pull/162.
Recent changes in poly2nb() had reduced and most
recently (1.1-8) removed the use of snap= in finding
candidate neighbours; many thanks to Matilda Brown for a clear and
well-documented issue #65
Add local Geary’s C #66 thanks to Josiah Parry, discussion on further work on #68
localmoran_perm() returns both look-up and folded
rank p-values
In poly2nb(), reverted removal of legacy interpreted
overlapping envelope code for sp objects that cannot be coerced to sf
without rgeos.
Add Fortran character handling USE_FC_LEN_T WRE
§6.6.1.
Checks OK with forthcoming deldir 1.0-0.
Fixes #62 clarifying dnearneigh() help page
knearneigh() and nbdists(); added
prototype adaptation to s2 for unprojected coordinates,
used if sf_use_s2() is TRUE which became the
default for sf 1.0.0
https://github.com/r-spatial/s2/issues/125. These are activated by
default.
dnearneigh() can choose the prototype
s2 approach if sf_use_s2() is
TRUE and use_s2=TRUE for unprojected
coordinates; from https://github.com/r-spatial/s2/issues/125 it seems
that distance thresholds at present use brute-force rather than spatial
indexing. Use is not activated by default.
poly2nb() now uses sf::st_intersects()
to find candidate neighbours unless findInBounds= is not
NULL. With spatial indexing, this is very fast and scales well for large
data sets. If sf_use_s2() is TRUE,
sf::st_intersects() passes the geometries to
s2::s2_intersects_matrix(), which also uses spatial
indexing and is very fast, scaling well for large data sets.
localmoran() and localmoran_perm()
return cluster quadrants in an attribute for three splits, zeros, means
and medians on the variable of interest and its spatial lag.
localmoran_perm() returns the skewness and kurtosis
of the permutation samples.
#55 related to #20 and cycling order in setting up grids provoked
re-design of interface to cell2nb(), with passing of
"GridTopology" or "SpatialGrid" objects as
unnamed first or x= argument. Coerce
"RasterLayer" or similar raster,
terra or stars objects to
sp class objects first if need be.
In working with renewing the arguments to cell2nb(),
it was useful to add tinytest support, which is now
present for this function and may be extended to other functions for
creating "nb" objects.

localmoran_perm() and localG_perm().
Adding nb2listwdist() contributed by René
Westerholt.
Adding use of sf through GEOS to find polygon
contiguity candidates in poly2nb() if geometry count >=
500 - uses intersections in polygon envelopes.
#38, #53 removing RANN, adding
dbscan suggestions for fast dnearneigh()
and knearneigh() via use_kd_tree= argument for
fast planar neighbour set finding in 2D and 3D. Affects
soi.graph() too, which had used
RANN.
#54 avoid partial matching in glist=
handling.
Disambiguating spdep and spatialreg model output object class names prior to making spdep model fitting functions defunct.
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.
