Disclaimer: I don't use R on Windows much myself. But: I can't help
noticing such threads occurring once in a while on r-help.
Why not simply define some folder to host one's personal library
*outside* of the main R library? As explained in ?Startup, one can put
something like
R_LIBS="<path_to_personal_library>:${R_LIBS}"
in a .Renviron file located in his/her HOME directory (see http://cran.r-project.org/bin/windows/base/rw-FAQ.html#What-are-HOME-and-working-directories_003f
for information on this). Then, install.packages() will, well,
install packages in this personal folder and R updates do not require
shuffling around of the library. At most an update.packages() once in
a while.
I have been using this scheme for a long time with much success (and
peace of mind) on Linux and OS X.
Hope this helps.

When I upgrade in Windows from say 2.6.2 tp 2.7.0 I do the following
1. Install 2.7.0 in a new directory
2 Rename the library subdirectory in the new version from library to
library2
3 Copy the library subdirectory in 2.6.2 to 2.7.0
4 Copy the contents of library2 to the transferred library. This
re-installs the updated base packages.
5 Within R run update.packages(checkBuilt = TRUE) and you will be
presented with a list of packages and be given the option of updating
each package.
This procedure is easy to implement. I have used it for several
updates and it has always worked well
Best Regards
John.

Hi,
Ouch! That really hurt. But I get the point.
Here's what I did now. I copied all the package folders from R2.6,
except
for the R.css file, and copied them into the R2.7 folder.
That's your problem. You've hosed the 2.7 libraries.
You need to reinstall 2.7. Only copy package folders from 2.6 if
they don't
exist in 2.7. If they already exist there, they've already been
updated.
The older packages may not work in 2.7, but once you run the
update.packages() function, you should get the latest versions.

In the process, I overwrote the common files that came with the
installation of R2.7.
Here's the output that I obtained in R2.7 :
library()
Error in unique.default(ans) : 2 arguments passed
to .Internal(unique)
which requires 3
update.packages(checkBuilt=TRUE, ask=FALSE)
Error: could not find function "update.packages"
My intention with my previous mail was to check and obtain
confirmation on
details like what I should do with the R.css file.
But I realise that I should have then restricted myself to that
single
question. That way, I would not be wasting the valuable time of
the R list
experts, from whom I have received a lot of help previously.
After reading the FAQ once again, I am guessing that the problem
could be
a case of the internet downloading functions failing.
As suggested in the FAQ, I tried the following commands :
"path_to_R\bin\Rgui.exe" http_proxy=http://gannet/
http_proxy_user=ask
Error: unexpected symbol in ""path_to_R\bin\Rgui.exe" http_proxy"
"path_to_R\bin\Rgui.exe" http_proxy=http://user:[EMAIL PROTECTED]:80/
Error: unexpected symbol in ""path_to_R\bin\Rgui.exe" http_proxy"
Should I run the above commands in R, or in the windows command
window?
Thanking You,
Ravi

This is not a reasonable request. Rather than trying those two
methods
one more time, and recording what goes wrong, you expect someone
on the list
to do it for you? If the advice was in the FAQ, presumably it
works for
others, so the reason it didn't work for you is likely that you
misinterpreted part of it, or your system has a unique problem,
etc. The
*only* way someone could diagnose that would be to see the error
messages.
You need to use some common sense when you're asking for help.
