useRs and developeRs-

Apologies for my naivety, but I just couldn't figure out how to open an old workspace (created using R 2.3.0) using R 2.3.0 and not R 2.4.0 which is currently happening. For all I know this has always been the case, but I'm having a problem with a function that doesn't work in 2.4.0 but does work in 2.3.1 (function is in the process of being fixed). So I would ideally like to open my old workspaces with the version of R I used in creating the workspace and at the moment not in R 2.4.0 - though in a few weeks when the function is fixed I'm sure I'll love 2.4.0 as I have all previous versions:)

Thanks for any help,

-Mat

Steps to what I'm doing.

  1. In R 2.3.1 I import data, manipulate it until my heart's content, and run some analyses.
  2. I save the workspace to my local drive - name it CoolStats.RData.
  3. I see R 2.4.0 is released and immediately download it and start playing with it only to find the above mentioned error.
  4. Since error is going to take some time to fix, will work with R 2.3.1 in the interim.
  5. Open CoolStat.Rdata and when I type version I get the below.
