[ESS] .Rdata not loading

[Tyler Smith]

Hi Rich,

ESS doesn't load data. All it does is pass commands to R. It looks 
like the command is getting successfully passed to R, so ESS is 
not likely the problem. You can confirm this by running the code 
in an R terminal (i.e., outside of Emacs). If the file still won't 
load, then you can rule out ESS as the problem.

If this is true, then the problem is with R or your .Rdata file. 
One plausible explanation from stackoverflow[1] is that your 
.Rdata file, being quite large, may not have completely saved 
before R quit last time you used it. If that's the case, there may 
be no solution other than re-generating the data from scratch.

Another possibility is your .Rdata was created by a version of R 
that's different from the one you're using today. That sounds 
unlikely since you haven't manually updated your R version. Is it 
possible an automatic update happened over night? You could 
recover from this by re-installing the previous version of R. 

Good luck!

Tyler
