R help - May 2007 - error message

Hi, 

I am trying to install the package exonmap and RMySQL however I keep
getting the following error:

"Error in library(pkg, character.only = TRUE) : 
        'RMySQL' is not a valid package -- installed < 2.0.0?"

I have R version 2.4.1 so I know its not a version issue. I deleted and
reinstalled the folders again and the same thing happened. Has anyone
any ideas?

Thanks, 

Karen

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

install.packages("RMySQL", dep=T)

should fix it for you.

ps: The error says RMySQL is the problem... it is not complaining  
about R itself (although it would not be a bad idea, given that the  
latest R is v 2.5.0, so it would be a better idea to start by  
upgrading your R)
