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: graphics

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.
