R CMD check file issues

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...

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

Loading required package: stats

Loading required package: splines



Attaching package: 'Hmisc'



The following object(s) are masked from 'package:survival':



      untangle.specials



The following object(s) are masked from 'package:base':



      format.pval, round.POSIXt, trunc.POSIXt, units



Loading required package: R2HTML

Warning in file(filename, "wt") :

    cannot open file
'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.
