Hi carol,
Have you tried renaming the file to something like "my.RData"? And
just how big is it?

Jim

yes and doesn't help.600MB
Thanks

There are several possible reasons and you have really told us nothing that might help isolating the problem. 600 MB is large, but not "very" large. R and your OS should not be expected to have a problem with files of that size. First of all, you'll need to document why you expect this should work in the first place.

- is the file where you think it is? ?dir
- do you actually have read access? ?file.access
- was the file produced by a program that writes correctly formatted Rdata files?
- does this work with other files that are similarly formatted?

etc.
