Hi Do you have 2 versions of .RData? If yes you probably need to install packages which were installed and used before saving old .RData file to be able to access this file with new R version.
If this does not help, you could return to previous R version, save necessary objects to separate .rdata file and load them to R 3.0.0 environment. see ?save, ?load Regards Petr > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-bounces@r- > project.org] On Behalf Of Luvalle, Michael J (Michael) > Sent: Thursday, August 29, 2013 4:33 PM > To: r-help@r-project.org > Subject: [R] Running pre R.14 version of R with R3.0.0 > > I upgraded R from 2.12.1 to 3.0.0 (on windows XP(, and as soon as I > saved the 3.0.0 workspace, was unable to access .Rdata from 2.12.1. > The message in the R console is "Error in loadNamesSpace(name): there > is no package called parallel" and a popup window that says "Fatal > error: unable to restore saved date in .Rdata" > > Is there anything that can be done to access the old .Rdata without > destroying the new? > > Thanks > > [[alternative HTML version deleted]] > > ______________________________________________ > 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. ______________________________________________ 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.
