Yes, R >= 2.4.0 use a different internal representation for new-style 
class objects.

If Windows, R itself is at:

http://cran.r-project.org/bin/windows/base/old/2.3.1/R-2.3.1-win32.exe

and sp at:

http://cran.r-project.org/bin/windows/contrib/2.3/sp_0.8-20.zip
(but install.packages("sp") in R 2.3.1 will choose that version)

Otherwise:

http://cran.r-project.org/src/base/R-2/R-2.3.1.tar.gz

http://cran.r-project.org/src/contrib/Archive/S/sp_0.8-20.tar.gz

as the most recent sp < 0.9 - use R CMD INSTALL sp_0.8-20.tar.gz from the 
command line for the old R engine. 

In either case install the old R engine somewhere locally, so that it will 
not damage your new installation, the same with sp. If need be, on some 
other machine.

Hope this helps,

Roger
