[R] echo Rprofile.site on startup

[Thompson, David (MNR)]

Hello,

I have not been able to find how to have R echo the Rprofile.site
contents to the console on start-up.
Changing the windoze shortcut to include the '--verbose' option does not
show what I am looking for.
I would like to see the options and commands listed, in addition to the
library() loadings, as they are processed. Examples of the type of
options I like and shortcut-commands (aliases) that I collect to shrink
my keystroke count are:

	options(digits=2)
	options(graphics.record=TRUE)

	# show head and tail together
	so <- function(x, n=20) { print(head(x, n)) ; print(tail(x, n))
}
	# shorthand for part of Sys.info() and sessionInfo()
	si <- function() { Sys.info()[c(1,2,3,5)] ; sessionInfo() }

I would like to view these as processed when I am changing options and
adding aliases so that I may know which parts are successfully/properly
defined.

Does the same process work for all of Rprofile.site, .Rprofile, .First,
.Last (, etc.?) profile files?

Is there a 'best practice' on which of the profile files one should use?
I use only the Rprofile.site since I am the only user on my PC.

Thanx, DaveT.
