Duncan,
I've pared down my .Rprofile so that it has just the options line, started R
from terminal (instead of using ESS-emacs) and I still have the problem. Am
I specifying the options incorrectly? I believe I took this directly from
the help page. See my output of .Rprofile, the code example that doesn't
work as we think it ought, and my sessionInfo(). Thanks, Mark
Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.

+ y <- x + 12
+ nonsense
+ y

> my.func(14)
Error in my.func(14) : object 'nonsense' not found
