Colleagues,
I am trying to understand how R (2.12.1) obtains the PATH environment variable
in Windows (7 or Vista). Startup {base} directs one to:
"R_ENVIRON" -- which equals "" in my systems
R_HOME/etc/Renviron.site -- which does not exist
Next, it directs to:
R_HOME/etc/Rprofile.site -- which also does not exist (the expected
behavior in a "factory-fresh" installation)
I found the following files in R_HOME/etc:
Makeconf
Rcmd_environ
Rconsole
Rdevga
respositories
rgb.text
Rprofile.txt
none of which refer to PATH (except Makeconf, which refers to JAVA path, but
not to PATH itself)
Today's R-SIG-Mac Digest addresses a similar issue in OS X -- that R.app gets
the values from /.MacOSX/environment.plist whereas a session started in
Terminal uses .bashrc or /etc/profile. What are the corresponding sources in
Windows?
Thanks in advance.
Dennis
