Hi all, No matter how hard I try (or Google) I cannot fix these warning messages (below) that I get repeatedly. I am new to this and have jumped straight in. None of the manuals, or webpages, seem to help. Can anyone here?? If anyone can, think of it as your good deed for the day!

Hi Huw, in R 2.11, the grep function changed & lost the extended argument. Since you didn't provide sessionInfo() it's impossible to tell which version of R you're running, but you should update your R & Bioconductor to the latest version. If you still get the error, then your should contact the package maintainer, or try to fix the problem yourself mark On 27/10/2010, at 4:01 AM, Huw Jones wrote: > Hi all, > > No matter how hard I try (or Google) I cannot fix these warning messages (below) that I get repeatedly.
