[R-sig-Geo] routine write.pointShape missing from maptools under R 2.10?

[reeves at nceas.ucsb.edu]

Hello List:

While testing some R scripts that use maptools/write.pointShape(), and which
run correctly under R ver 2.9 (and earlier), I encountered:

package 'maptools' successfully unpacked and MD5 sums checked

The downloaded packages are in
        C:\Users\visitor.rover19\AppData\Local\Temp\RtmpLg4gih\downloaded_packages

Executing the line:
#
# rgdal loads sp
#
     require(rgdal)
     require(PBSmapping)
     require(maptools)
.....

gives:
     write.pointShape(coordinates=coordinates(cbind(PolyCentPBS[,2],PolyCentPBS[,3])),PolyCentPBS,FullName)

Note that this script workes correctly under R 2.9 and earlier....



no methods for 'write.pointShape' and no documentation for it as a function

looking for documentation gives:

Error in .helpForCall(topicExpr, parent.frame()) :

The complete run-time output is given below......

When I ran the

Is write.pointShape still supported under R 2.10?
