[R-sig-Geo] Editing Shapefiles

[Malcolm Campbell]

I am using the packages shapefiles, and maptools in R to visualize data
from shapefiles, dbf files, and census data.

My question is this, is it possible once a shapefile is read into R, to
edit the contents of the shapefile?

Let me give a practical example.

I am using a shapefile of electoral wards in England and I would like to
be able to remove some of the wards from the shapefile in order to have
a smaller shapefile of wards, for example, London wards only. After
reading susbstantial amounts of documentation and related articles and
numerous web searches I have so far been unable to find an answer.

 

Responses would be greatly appreciated.
