added remove.self()
, thanks to Josiah Parry #83.
unescape underscores in help pages
replace deprecated S-compatibility macros DOUBLE_
#81 improved dnearneigh()
help page.
#79 remove "htest"
class from LOSH.mc()
output object.
Added GA SI article to citations.
Replace rainbow()
by hcl.colors(..., "Set 2")

Add link to R-sig-geo thread on EBlocal()
NaN estimates when many counts are zero on help page.
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.
#58 contributed by Jeff Sauer and Levi Wolf (from https://doi.org/10.31219/osf.io/ugkhp) providing conditional standard deviates for local Moran’s I
Error in assignment to matrix detected by CRAN check in SIDS vignette, section on median polish
Changes to continuous integration and vignettes.
Error in poly2nb(, queen=FALSE)
in sf grids (double counting of closed polygon start/end points), https://github.com/r-spatial/spdep/issues/50, thanks to Christopher Kenny.
Adding local Moran and local G conditional permutation: 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.
