I don't have much idea about the error. Hopefully someone else can
shed more light. I'll just give some generic info. The "ideal" way to
have the latest R and a working rkward is to install R from:
http://cran.r-project.org/bin/linux/ubuntu/  (and not form ubuntu's repo)

Then, install the corresponding "rkward-cran" from Meik's repo. See here.
http://sourceforge.net/apps/mediawiki/rkward/index.php?title=Binaries_and_Build_Scripts#KDE4_versions:

If you happen to have done something else, can you clean (purge) both
R and rkward and try the above steps?
