         I'm running R 1.15.0;  sessionInfo() appears below.  I get this
from Rgui i386 and x64 plus when calling Rterm x64 via GNU Emacs 23.3.1
using ESS.

I can see three possibilities:

  1.  You have more than one Rprofile.site, and it's not reading the
one you think it's reading.   The search order is:
   - the file mentioned in the R_PROFILE environment variable if there
is one
   - RHOME/etc/<arch>/Rprofile.site
   - RHOME/etc/Rprofile.site

It takes the first of those and ignores later ones.

<arch>  is either i386 or x64, depending on your architecture.

2.  You don't have permission to read the file.  Does readLines() read
it from within a session?  This code is somewhat like what R does on
startup:

   env<- Sys.getenv("R_PROFILE")
   if (nchar(env))
     readLines(env)
   else {
     filename<- file.path(R.home(), "etc", sub("[/]", "",
Sys.getenv("R_ARCH")), "Rprofile.site")
     if (file.exists(filename))
       readLines(filename)
     else {
       filename<- file.path(R.home(), "etc", "Rprofile.site")
       if (file.exists(filename))
         readLines(filename)
     }
   }

Does it work for you?

        Thanks very much.  It helped me isolate and solve the problem:


        I edited "Rprofile.site" in Emacs.  When I saved the edited
version into the default, write protected location, Windows 7 apparently
saved two copies:  the original and a hidden copy with my edits.  When I
then reopen the file in Emacs, I see my edits.  However, when I open it
with WordPad or try to read it as you just described, my edits do not
appear.  Knowing this, I saved a copy to a non-protected location,
edited it there, then copied the edited version back into the protected
directories.  Now it works.  (I had previously avoided installing R in
the default location since encountering problems with Vista.)


        This is almost enough to drive a person to join the "I hate
MicroSoft" fan club.

3.  There's a bug somewhere....

Hello All:


            I'm still unable to get Rprofile.site to set, e.g.,
options(max.print=222), as I did with previous versions of R.


            I just found similar questions posed by Trevor Miles and
Ross
Bowden with replies by Uwe Ligges and Duncan Murdoch.


            In addition to the things I tried documented below, I
also copied
Rprofile.site into "R_HOME/etc/i386" and "R_HOME/etc/x64", without,
e.g.,
max.print being changed to 222 as requested.


            Any other suggestions?


            Thanks,
            Spencer Graves

        I have so far failed to get Rprofile.site to be processed in
R 2.15.0
under Windows 7 as I remember having done it in previous version of
R.  For
example, I've included "options(max.print=222)" in
"R_HOME/etc/Rprofile.site" (with and without the environmental
variable
R_HOME set to the install directory of R 2.15.0 in advanced system
settings):  When I start R, I still get the default:


options('max.print')
$max.print
[1] 99999


        Suggestions?
        Thanks,
        Spencer
