You're correct in thinking that it's a version problem and I'm pretty
sure that upgrading to the latest version of R (2.12) will solve your

It looks as if the MEDIP package was just released in bioconductor 2.7
(which is only meant to run on R 2.12), so I guess you installed MEDIP
by some "other" (not supported) means?

Keep in mind that using biocLite to install your packages is probably
the best way to ensure that you don't run into versioning problems, so
go ahead and:

(i) download/install the latest R;
(ii) biocLite() your way into the base bioconductor install; and
(iii) biocLite("MEDIP")

You should be good to go after that.

Hope that helps,
