Dear helpeRs,

on my Windows 7 laptop, I have problems getting R CMD check to work.

I

believe it did work completely before, but I am not sure.

Yesterday it almost worked, except for the tests: These were aborted
because of a complaint that the temporary directory wasn't

available. I

played with windows environment variables for the temporary

directory,

but that didn't solve it. Apparently I did something that made

things 

worse:

Today, R CMD check completely refuses to work, with the error

message

"Fatal error: creation of tmpfile failed -- set TMPDIR suitably?"

This

is the same for current R and R-devel. Changes to the TEMP or TMP
environment variable don't influence this behavior.

The path:
C:\Rtools;C:\Program Files\Dell\DW WLAN Card;C:\Program

With the default install, there are no executables in C:\Rtools. They

are normally in C:\Rtools\bin and C:\Rtools\gcc-4.6.3\bin. But this 
probably isn't causing the problem.  It sounds as though you've set 
the temporary directory to something that doesn't exist, or somewhere

you're not allowed to write.

Can you still start R?  If so, what does tempdir() show?  Mine shows

[1] "C:\\temp\\RtmpGeoCGq"

The random bit at the end would be different for each session. The 
part before needs to be a path in which you have write permission.

Actually, I can't start R any more (Error: mkdir R_TempDir does not 
work). And it appears that changing the TEMP and TMP environment 
variables in Windows does not really affect the choice of TempDir in R
? 
Yesterday, the complaint was always related to a random directory name 
within the default temporary directory, and there are many such 
directories in that path (I would have thought that these are deleted 
when shutting the machine down, but apparently the are not), so there 
must have been write permission in there once. Today everything is 
different, perhaps because of something I did yesterday but don't 
remember any more.

If all else fails, I suppose the fastest thing may be a complete 
re-install of R.

Any ideas what I can do to fix this?
Perhaps also relevant: I run R CMD check from a DOS window that is
opened with administrator rights.

You should start R from the same window, using just "R" or "Rgui" to 
make sure it sees the same environment.
