if CRS is NA, do not require (and depend on) presence of package sf; #144
remove use of deprecated is.R()
remove startup message
get_evolution_status() defaults to 2, meaning sp will no longer call rgdal or rgeos; spTransform will work using sf::st_transform.
increase R version required from 3.0.0 to 3.2.0, which was de facto already required (PR from Sebastian Meyer)
add evolution vignette, drop over vignette, add startup message
add get_evolution_status() and set_evolution_status()
merge the evolution branch from rsbivand/sp@evolution
remove S-compatibility DOUBLE_* macros; https://github.com/edzer/sp/pull/115
add CRS cache and update CRS print method; https://github.com/edzer/sp/pull/103
Adding a wkt() method and muting internal warnings; https://github.com/edzer/sp/pull/76
warn on NULL projargs in CRS(); https://github.com/edzer/sp/pull/74
prepare for new (>= 1.5.1) rgdal, which creates and listens to a comments() field of a CRS object carrying a WKT representation of a CRS rather than the proj4string; @rsb, https://github.com/edzer/sp/pull/67 and https://github.com/edzer/sp/pull/69 ; for more info see e.g. https://github.com/edzer/sp/issues/68 and https://github.com/r-spatial/discuss/issues/28
fix length > 1 in coercion to logical error; #54, #60
add is.na method for CRS objects
address error in spplot, leading to display of "Error using packet 1: mixture of missing and non missing values for cex"
address warning from Tomas Kalibera's static code checking
fix bug in duplicating objects in C; see https://github.com/edzer/sp/commit/8f8a66090e47cf0f6bbf5549376c0bc07b6c29df
fix all long/lat-based great circle distance functions; see https://github.com/edzer/sp/commit/d8374ff7efc6735cba9a054748c602bed0672f23 and https://stat.ethz.ch/pipermail/r-sig-geo/2016-December/025201.html
clarified cellcentre.offset documentation, see https://github.com/edzer/sp/issues/18
update sp gallery, see https://edzer.github.io/sp/
move methods from Imports: to Depends:
improve base plot methods for SpatialGridDataFrame and SpatialPixelsDataFrame objects, see https://r-spatial.org/r/2016/03/08/plotting-spatial-grids.html for examples
improve the graticule labels methods, see ?gridlines
fix hole assignment for triangles, reported in https://stat.ethz.ch/pipermail/r-sig-geo/2016-March/024214.html
as.SpatialPolygons.GridTopology drops rownames of coordinates generated, but keeps coordinate (column) names from the cellcentre.offset slot of the grid
improve examples in over vignette.
method 'row.names' for 'SpatialPoints' makes unique row names, or drops them.
add a labels method for gridlines, drawing labels under varying angle (see gridlines example)
add coercion (“as” methods) from deldir to SpatialLines and SpatialPolygons
migrate sp code base to github
correct [ subsetting when i is all FALSE; report by Francois Rousseau.
add geometry<- method for Spatial, wrapping addAttrToGeom
addressing rbind and docs issues raised by Kent Johnson on r-sig-geo, 5 Dec 2015
get 'row.names' of coords correctly if object is a SpatialPoints
add non-default coercion SpatialPolygonsDataFrame to SpatialPolygons
add comment to SpatialPolygons coerced from SpatialGrid or SpatialPixels
coordinates method for SpatiaLines now retains rownames
spsample.Spatial does no longer generate objects with rownames.
CRS gains argument doCheckCRSArgs, to allow suppression of the default checking
coercion from Lines to SpatialPoints now drops (duplicate) rownames
add coercion from SpatialLines* to SpatialMultiPoints*
improve printing of SpatialMultiPoint* objects
aggregate now passes minDimension to rgeos; explanation of
aggregate extended in its vignette
depend on rgeos version 0.3-13
merge now accepts "row.names" or 0 for arguments by.x or by.y, for compatibility with base::merge.
aggregate now accepts parameter minDimension, introduced for over in 1.2-0, and passes it on to over to control when features intersect; see the documentation of over and its vignette for details.
SpatialMultiPoints objects with zero features can now exist.
Support for SpatialMultiPoints and
SpatialMultiPointsDataFrame objects. Where SpatialPoints
are set of points, SpatialMultiPoints are sets of point sets.
SpatialPointsDataFrame objects bind points to attribute values,
SpatialMultiPointsDataFrame bind point sets to attribute values.
Methods supported are subsetting ([),
plot, spplot, over, and coercion to
SpatialPoints or SpatialPointsDataFrame. Functions in
rgeos support this feature class. See also demo(mp).
creating SpatialPoints objects with duplicated coordinate
rownames now gives a warning, which will become an error in the future.
Support for Google Earth or OpenStreetMap background maps in
sp::plot and spplot. Maps returned by
function GetMap in package RgoogleMaps
function get_map in package ggmap
are now understood by plotting functions in sp. In particular,
sp::plot now has an argument bgMap, spplot
now has panel functions panel.RgoogleMaps and panel.ggmap;
See demo(webmap) for examples.
As these maps assume a web mercator projection, sp::plot issues a warning
if the object to be plotted have a CRS that does not contain "+init=epsg:3857"
over methods that are taken care of by rgeos (anything
involving SpatialLines, or SpatialPolygons-SpatialPolygons)
gained an argument minDimension, which causes an ordering of returned
features by dimension of intersection, and the ability to select a minimun
dimension (e.g. only area-overlap); this uses gRelate, and has a
computational cost. Documentation found in vignette("over").
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.
