[R] problem with the .Rhistory

[Rolf Turner]

I recall having a similar problem a while back, and it turned out
that it was due to command line editing not being available.  This in
turn was due to a problem with the readline package.  I think we had
a flakey version (obtained as a Sun package?) and when we got another
version (from GNU?) and installed it --- and then rebuilt R ---
command line editing (and savehistory()) worked fine.

Sorry to be vague, but I don't have good records of what went
on, and it was a couple of years ago.

Check on command line editing first --- in R execute

	capabilities()

and if ``cledit'' turns out to be FALSE, then readline is probably
your problem.  Peter Dalgaard may be able to give you better insight
as to how to fix it.
