[R] maptools: using to sets of information (within two shape files) for one plot

Please let us know at least what package/s you are using to read the
data from shapefiles and the code you are using.
The two data sets may be using different projections, so use
summary(obj1) and summary(obj2) to describe their projection metadata
and data extents (well, at least if they are Spatial* objects from the
sp package). With sp/rgdal, or other packages these can be reprojected
if you know the original coordinate systems so that plotting them
together makes sense. There are good resources and vignettes sp and
related tools that explain this, and a dedicated mailing list for data
like these (R-Sig-Geo).

Cheers, Mike.
