Hi Michael, RData files created by save() or save.image() are compatible across versions.
It sounds to me as if you overwrote your RData file, rather than anything to do with R versions. If the same filename is used, the RData file is overwritten, not appended to - only whatever is currently in your workspace. So if you used "save workspace image" with the default name, it would simply replace any previous workspace image in that directory. You can use save.image() with different names from the command line, and load as many separate RData files into your session as you'd like, although objects with the same names will be overwritten in your workspace. Also, pleae note that this is a more appropriate question for the main R-help list. Sarah On Wednesday, July 18, 2012, Michael Trianni wrote: > I recently installed R version 2.14.1.
