[R] error message

[Martin Morgan]

Hi Karen --

This sounds like a Bioconductor question, and should be sent to the
Bioconductor list.

http://www.bioconductor.org/docs/mailList.html

Likely the complaint is about RMySQL being too old, rather than R. The
idea of 'reinstalling folders' doesn't sound like a good strategy for
updating packages; for Bioconductor see

http://www.bioconductor.org/docs/install-howto.html

likely

> source("http://www.bioconductor.org/biocLite.R")
> biocLite("exonmap")

does the trick. If not and the problem seems to be RMySQL, then try

> biocLite("RMySQL")

or in a more robust way update all of your currently installed
packages with

> library("Biobase")
> update.packages(repos=biocReposList())

Finally, please provide a more informative subject line and the output
of

> sessionInfo()

so that the community can get a better understanding of the platform
and packages you're using, and hence the source of your problems.

Best,

Martin
