Subject: [Rd] R-admin docs, Installing packages (PR#1554)
Message-ID: <200205141513.RAA21776@pubhealth.ku.dk>

In the R-admin document, at "Installing packages", it says:

  To install packages from source on Unix use

  R CMD INSTALL -l /path/to/library pkg1 pkg2 ...

  The part -l /path/to/library can be omitted, when the first library in R_LIBS
is   
  used if set, otherwise the main library R_HOME/library.

1.  Can I suggest re-wording this last sentence?  Replace "when" by "in which
case", and add "is used" at the end.  I puzzled for quite a while before I
understood what the present wording meant (and I hope I got it right!)

2.  I got confused also because although my .Renviron has
R_LIBS=/Users/david/Library/R
and that works when finding packages within an R session, when I use R CMD
install  without the -l /path/to/library part, packages still get installed in
R_HOME/library.  Am I right to conclude that .Renviron is not used by R CMD
install, and that R_LIBS has to be set by some other method before installing
packages to a private library in this way?  This could be clearer in the
documentation I think.
