suppose I want to ensure a variable is set to a certain value in
.Rprofile, how can I be sure that R.data won't overwrite it? It just
seems like loading .Rdata after .Rprofile makes it difficult to change
things easily.
# ~/.Rprofile
cat("Running my .Rprofile...");
library(modreg)
cat("Running my .Rprofile...done");

Subject: [R] .Rprofile, .Rfirst, and .Rdata
Hi all,
After a short hiatus away from R I have found that it's
changed a bit.
I used to keep a definition of .First in .Rprofile that did a
couple of
things on startup (load a couple of libraries). Now, I've discovered
that when I change the definition of .First in .Rprofile it doesn't
change anything when I start up, because .First is held over
in .Rdata
from the last session. The manual states that now .Rdata is loaded
last, as intended. My question is, how do I change what's in
.First (or
any other variable, for that matter), if .Rdata will always
override my
changes? (I'd prefer not to have to do it manually, and I'd prefer to
have all the other data preserved, rather than just leaving
out .Rdata)
Dave R.
