R devel - Jul 2009 - Checking package on Windows (and seemingly irreproducible errors in CRAN checks)

Hello,

I submitted a small package, colbycol, to CRAN. I developed it on Linux
and tested it on my Linux box and another Windows machine. Besides,
other people kindly tested it in their systems. 

The package seems to "compile" correctly in r-forge for Windows. In
fact, you can find the binary package at

http://r-forge.r-project.org/R/?group_id=426.

However, in CRAN, the Windows package cannot be built according to

http://cran.r-project.org/web/checks/check_results_colbycol.html

I cannot reproduce the error. I can guess very little more about what
could have gone wrong. The error seems to happen at a time when R tries
to read a temporary file (in a temporary folder) that has just been
created in a call to a non-R piece of code that does not catch its IO
exceptions, if any. 

Any ideas? Suggestions?

Best regards,

That's a check error.  Did you try running R CMD CHECK on it?

Since it appears to happen in an example you could put
\dontrun{
...
}

around the example although it would be better to get it to the
state that it passes R CMD CHECK without having to do that.

Dear Carlos,
>From your check results:
        cbc.data <- cbc.read.table( system.file("data",
        "cbc.test.data.txt", package = "colbycol"), sep =
"\t" )
                Warning in file(file, "r") :
                cannot open file '0001': No such file or directory
        
I think you're trying to read the file "cbc.test.data.txt" located
in
the folder "data" of your package skeleton. Is that right? If so,
maybe
using

        paste(system.file(package = "colbycol"),
        "data/cbc.test.data.txt", sep="/")
        
will solve your issue - although I didn't try.

Best,
Mathieu
