Dear Duncan, dear Gabor,
Thank you for this additional information and all these great tips.
Setting the system path in the following way solved my problem:
c:\Rtools\bin;c:\Rtools\perl\bin;c:\Rtools\MinGW\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;c:\Programme\Microsoft
SQL Server\90\Tools\binn\
Luckily this solves also the problem with potential conflicts between R
tools, Microsoft tools and ROOT, so that I do not have to rename any
tools (which I would be reluctant to do).
Since at the moment everything seems to work fine, and I am no Windows
expert (I do all my development on my Mac), I will keep the current
setting, however, the next time I have to set up everything, I will try
to take advantage of Rcmd.bat since Gabor mentions that it will not
override any of my settings.
Regarding the R installation documentation, I understand now that this
seems to be a problem of my complicated setup and not a general problem,
so adding this information may confuse other people.
Best regards
Christian

Dear Duncan
Thank you for this explicit explanation, you are right:
When setting the system variable "Path" (as administrator) in addition
to setting the user variable "PATH" (as user), now everything works fine.
Interestingly, setting the system variable "Path" on my laptop with
Rtools27 seems not to be necessary.
May I suggest that this could be clarified in "R Installation and
Administration" since there only the user variable "PATH" is mentioned (as
far as I see).
In a shell there is only one PATH, so the manual is correct.
I did not say that the manual is not correct, I only suggested to clarify
the issue, since when running R CMD INSTALL from the Command Console I need
to set also the system variable "Path".
I'd be reluctant to do this, for the same reason Brian was: the
documentation is correct. You need to set the PATH environment variable
correctly, and that's what we say. The fact that doing this is complicated
and confusing on Windows is a problem with the Windows design and
documentation, not the R documentation, and Microsoft certainly has more
resources than we do to address it. What was their response when you asked
them to improve their documentation?

The http://batchfiles.googlecode.com home page does give some tips for setting
paths just in case. Of course if you are using the batchfiles you
won't have to set
any paths in the first place.
