Thank you both very much - that's what I needed to know. One question,
though - is there an R.conf or something, where the default is format of
that filename is set? I've looked through the rpm for R-core, and what
.../etc/... files are in it, and I don't see that. Is there such a config,
or is that hard-coded into R itself?
