This does not fix a major part of the problem. When the user installs
a new version of R, it goes into the version-specific directory, the
user has 2 R's, can't figure what to do about the installed packages,
I guess, at the base of it, I don't see why you want the versioning in
the install dir's name, except for developers who need to keep several
installed at once.
And, if we persist installing into version specific paths, we can't
ever just put one permanent R directory in the PATH variable, and we
have to keep wrestling with the problem that the user wants to run
Rterm.exe from the "command line" and it is not in the path so it does
Other users mention mischief in Win7 that I don't see. On my win7
systems, either 64 bit or 32 bit, there is no trouble at all
installing the 32 bit version of R into "C:\Program Files\R" and
putting into the path "C:\Program Files\R\bin\i386". I don't have the
complications people mention about the system resisting that choice.
The system does have the two parallel sets of directories, ("Program
Files" and "Program Files (x86)", but on either 64 or 32 bit
systems, the 32 bit R gets found. (I install the 32bit because the R
web site still recommends that, except for RODBC users).
What is the other problem you are referring to?
The only big Vista/Win7 complication I see is that "VirtualStore"
disaster. When I try to configure something in ESS or install an R
package and I'm not acting as the administrator, then Windows tries to
"fool me" by installing the app in a hidden part of the user account,
in a folder named like
C:\Users\pauljohn\AppData\...\LocalSettings\VirtualStore\. Then it
creates an "illusion" that it did install into C:\Program Files\R by
re-routing my user requests from the C:\Program Files area into that
VirtualStore. So after I log off, then other users come along and R
packages or Emacs ESS config changes I made are not available to them.
It really pissed me off when I spent an afternoon customizing Emacs
and all the changes seemed to disappear when somebody else logged on.
It seems willing to let you edit files in C:\Program Files\Gnu Emacs
23.2\site-lisp\site-start.d, but the changes you make by hand get
diverted into that hidden VirtualStore thing. But, as long as you are
aware of this shell game, you can run Emacs "as administrator" so it
will actually make the changes you want in the Program Files
hierarchy. Well, it is still a ghastly, horrible setup. But I'm warned
about it now.
