(a) Yes, it's the wrong group. R-help is for general R questions like
this. R-gui for discussing graphical user interfaces.

(b) Workspaces are just that. They contain a set of objects created by
computations, not how they were generated. To see what has been done,
there may be a supplemental .Rhistory file, or the original .R script
file (+ raw data files).

(c) You don't really want to know the structure of .RData files. They
contain a serialized encoding of internal R structures. The gory details
are in the source code (src/main/serialize.c), if you insist.

(d) Now why didn't he just do diff(log10(1:10)) ?
