I guess you have figured out that if you save with <name>.Rdata or
<name>.Rdta and try to load() as "<name>.RData", the combined R-MacOS
software is not going to give you what you expect. If on the other
hand you had click-hold-dragged those .RData files to the R icon on
your Dock, you may have gotten the expected behavior.
You can change the file extensions which will be recognized (although
not necessarily displayed with the proper R-icon inFfinder windows) by
changing the default programs in a GetInfo window from the system.
I also checked to see what would happen if I changed the extension to
".junk" and then dragged .... Turns out that the R interpreter
searches for a file named test.r and when it finds it it loads it into
an editing window. (That was _not_ what I expected.)

Steven,
I have exited my R session and restarted and I can load the file
without issue. I have also tried loading the saved data on some
older
versions of R (2.10.1 and 2.11.0) and Windows (XP). Have you tried
recreating the test object, ensuring that it is not NULL itself,
resaving it, and then see if loading it works better?

That worked for me once I properly quoted "test.RData" on

If correcting the quoting does not help you, perhaps you can report
the results of sessionInfo()
Cheers,

In the particular application I have I save "test.Rdata" to a sub
directory
dir<-"Example"
dir.create(dir)
test<-data.frame(a=c(1,2,3),b=c(3,4,5)
full<-file.path(dir,"test.Rdata,fsep=.Platform$file.sep)
save(test,file=full)
load(full)
returns NULL
it works fine when the object is saved to the working directory,
but
fails
when saved to a sub directory.
The Rdata is there. Bytes are in it. but loading it doesnt work.
