instructions on how to install it? (I didn't see anything about this on
CRAN.) I'm running R-base-1.8.0-1.i386.rpm (the most recent binary
available for SuSE) and it appears to have the 'valueClass' problem.
Thanks,

However,
there is a problem in the released version of R 1.8.0 that affects
the DBI and other packages (has something to do with methods
that use the "valueClass" argument in the setGeneric/setMethod functions).
In this case one needs to use the R-patched version.
Hope this helps,

Since there doesn't appear to be an RMySQL rpm for SuSE 8.*, does
anyone know if the 7.3 version will work with the SuSE 8.2 rpms of R and
DBI?
The package installs without complaint, but when I try to run
con <- dbConnect(dbDriver("MySQL"),dbname="test")
I get the error
Error in dbConnect(dbDriver("MySQL")) : couldn't find function
".valueClassTest"
(This is my first attempt to access a an rdms from R, so I could be
doing something else wrong.)
Any ideas as what might be generating this error, or as to combinations
of rpms that will work under SuSE 8.2 would be appreciated. (I took a
stab at compiling RMySQL from src, but I don't have MySQL src installed
and I rather not get involved in this if I can avoid it.)
Thanks,

There was a discussion about it just after R-1.8.0 was released. Patched
version may be found at CRAN (as usual). For example
ftp://ftp.stat.math.ethz.ch/Software/R/R-patched_2003-10-*. You can
either compile it from scratch or fix your available installation just
adding a line exports(.valueClassTest) to the end of NAMESPACE file in
the methods library (this works for me).
