Changes in version 1.2-2 (2016-02-05) o method `row.names` for `SpatialPoints` makes unique row names, or drops them. o add a labels method for gridlines, drawing labels under varying angle (see gridlines example) o add coercion (``as'' methods) from deldir to SpatialLines and SpatialPolygons o migrate sp code base to github o correct [ subsetting when i is all FALSE; report by Francois Rousseau. o add geometry<- method for Spatial, wrapping addAttrToGeom o addressing rbind and docs issues raised by Kent Johnson on r-sig-geo, 5 Dec 2015 o get `row.names` of coords correctly if object is a SpatialPoints o add non-default coercion SpatialPolygonsDataFrame to SpatialPolygons o add comment to SpatialPolygons coerced from SpatialGrid or SpatialPixels o coordinates method for SpatiaLines now retains rownames Changes in version 1.2-1 (2015-10-18) o spsample.Spatial does no longer generate objects with rownames. o CRS gains argument doCheckCRSArgs, to allow suppression of the default checking o coercion from Lines to SpatialPoints now drops (duplicate) rownames o add coercion from SpatialLines* to SpatialMultiPoints* o improve printing of SpatialMultiPoint* objects o aggregate now passes minDimension to rgeos; explanation of aggregate extended in its vignette o depend on rgeos version 0.3-13 o merge now accepts "row.names" or 0 for arguments by.x or by.y, for compatibility with base::merge. o 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. o SpatialMultiPoints objects with zero features can now exist. Changes in version 1.2-0 (2015-09-08) o 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). o creating SpatialPoints objects with duplicated coordinate rownames now gives a warning, which will become an error in the future. o 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" o 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.
