Hello Uwe, and thanks for your interest in the issue.
There is most certainly not another process that stops working between the
two R CMD check calls (recently, I've made a habit out of being ready to
press<up arrow> <enter> in the seconds after running my first R CMD check,
to rerun it if it fails).
At worst, there may ever have been an explorer window open, but this is
definitely not always the case, and I'm sure this window was not closed
then, between the calls.
I'm really quite afraid it is more of a windows issue than an R issue, but I
was hoping you wizards might have a workaround (apart from the obvious
suggestion to install Linux), as it is immensely annoying...
I have not seen this problem so far (but then, I am mostly under Windows
XP and winbuilder is Windows Server 2003).

Are you sure there is no other check process or editor that locks the
file?

This problem is likely to be specific to Windows, and particularly
Win7.
After a successful build of a package (R CMD build addendum), I
immediately
run an R CMD check for the same package.
Not always, but _very_ often, I get the following error:
C:\Users\nisabbe\Documents\@Doctoraat\R>R CMD check addendum
Loading required package: tcltk
Loading Tcl/Tk interface ... done
Loading required package: Hmisc
Loading required package: survival

The following object(s) are masked from 'package:survival':
untangle.specials
The following object(s) are masked from 'package:base':

Loading required package: R2HTML
Warning in file(filename, "wt") :

'C:/Users/nisabbe/Documents/@Doctoraat/R/addendum.Rcheck/00ch
eck.log': Permission denied
Error in file(filename, "wt") : cannot open the connection
Execution halted
If, after this, I immediately reissue the R CMD check command, it
works,
without the error.
I think this has something to do with how Win7 processes file
handling
(there are known issues even noticeable in windows explorer), but
perhaps
there is a way of circumventing this? It would be greatly
appreciated, as
this issue is preventing automation of build/check/install scripts.
Suggestions will be greatly appreciated.
