Hi! I just installed the latest R 3.01. I then wanted to update my packages. I believe the advice given is to take the library folder from the old R version and copy it on top of (overwrite) the library folder of the new R version, in my case the library of R 2.15.2 to library of R 3.01.
When I did this, the next time I started R 3.01, I had an error message Error in .Call("R_isMethodsDispatchOn", onOff, PACKAGE = "base") : "R_isMethodsDispatchOn" not available for .Call() for package "base" also the update.packages() function was 'not available'. Where did I go wrong? I think I will just update the packages I want rather than the whole folder and see if this works, Pancho Mulongeni Research Assistant PharmAccess Foundation 1 Fouché Street Windhoek West Windhoek Namibia Tel: +264 61 419 000 Fax: +264 61 419 001/2 Mob: +264 81 4456 286 ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
