This is not the way my version of R62 is functioning. I am using the
default installation except that I slightly modified Rprofile in the
library/base/R directory as my site file (as I do with each new
version). It is definitely reading this file (as it did in R61) and
not the etc/Rprofile mentioned in the faq (I have not checked if the
latter even exists). When I reinstall the base library, my
modifications are overwritten. I have not set the environmental
variable because up until now no environmental variables have ever
worked for me (eg for -v and -n) in previous versions of R.

PS I am getting some rather strange errors in R62 but have not yet
been able to track them down as reproducible: stack overflow when I
assign a class to a matrix, errors about wrong tags for every
instruction I type so that I have to leave R. If I can find
reproducible examples I shall report them.
