Current location of the Srings object (or its replacement)?
Rick, this change has been done a while back already -- substitute: Srings with Polygons Sring with Polygon see also the article about sp in the latest R-News issue. Best regards, -- Edzer

Hello all:
Following is a code sample that used the Srings class,
and which used to work before I upgraded to the
latest build of the 'sp' package and removed the
spmaptools package from my build.
Now, running this code generates the error:
Error: couldn't find function "Srings".
Even loading the spmaptools package does
not resolve this problem.
Any suggestions on resolving this issue?
Thanks, Rick Reeves
Now, R reports that
