Hello,
The issue is no longer an issue concerning my package as I have
changed the part that drives the error (for unrelated reasons).
It is true that I might have done a greater effort to make the package
fully cross-platform. I did R-CMD-checks on Unbuntu and CentOS but
never on Windows. But I did install the package on Windows and
successfully run, among other, the examples that fail on CRAN servers.
What makes me curious about Windows is how can it be that the checks
pass on some machines (r-forge´s) but fail on CRAN´s. If there were
any blunt violation of cross-platform implementation practices, all
Windows checks would fail. However, some succeed.
Perhaps this is an idle intellectual exercise. But one can probably
ask himself the following two questions:
1) If I R-CMD-check my package on _my_ Windows box, how can I be sure
that the check will also succeed in other Windows box?
You cannot (same as for any other OS where some settings are different
between machines). It might also be related to the fact that my Server
runs Windows Server 2008 64bit, due to permission problems, or due to
third party requirements (Java / Phyton that are not correctly
satisfied) - which is why I asked you to specify the requirements that
makes it work under your machine.
Best,
Uwe Ligges
2) Is there any lesson to learn concerning cross-platform
implementation to learn from this case (there seems to be and I am
learning it, by the way).
Best regards and thank you for your comments on this issue.

Dear Uwe,
The thing that I find funny is that the check of the package on
Windows for R 2.10.x works on r-forge as you can see here:
http://r-forge.r-project.org/R/?group_id=426&log=check_x86_32_windows&pkg=colbycol&flavor=devel
May I be facing some kind of Windows configuration specific issue
here? I am sorry that I am very Windows-illiterate...
Just from the plain output I suspect that the problem is handling of paths
in the 3rd party system used (Python) is different from R's on Windows and
the package author is not converting them properly. It seems as if Python is
trying to use the path 'd:/temp/Rtmp1mB6qg/dir72ae2cd6' literally instead of
using 'd:\temp\Rtmp1mB6qg\dir72ae2cd6'. I'm a bit surprised, because Java
does the right thing: System.out.println("'"+(new File("z:/foo/bar"))+"'");
will print correctly 'z:\foo\bar'.
I would suspect that the difference between R-Forge and CRAN may probably be
just the setting of TMP/TEMP... [just a guess ;)]
Cheers,
Simon
This is not something that worries me much "per se", as I am implementing
some changes in the package and the new version does not resemble the
current one too much, but intrigues me quite a lot.

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.
It won't slve it, because reading that file works, but reading file
"0001"
does ot which is handled within cbc.read.table() in the lines
....
for( column in names(columns) ){
tmp <- read.table( columns[[column]]$filename, sep = sep,
na.strings
= "", comment.char = "", quote = "", header = FALSE, ... )[,1]
....
I guess the problem happens before during the Java stuff where the 0001
file
is never created (at least not in the location you expect).
On the console I see error messages like
Exception in thread "main" Traceback (most recent call last):
File "d:/temp/colbycol/python/colbycol.py", line 6, in <module>
os.chdir( work_dir )
File "D:\RCompile\CRANpkg\lib\2.9\rSymPy\jython\Lib\os.py", line 261, in
chdir
raise OSError(errno.ENOENT, strerror(errno.ENOENT), path)
OSError: [Errno 2] No such file or directory:
'd:/temp/Rtmp1mB6qg/dir72ae2cd6'
