bulding a package for Windows (path problem?)

Thanks to Duncan Murdoch and Prof. Ripley for the previous answers. I
apologize as I was not updated with the R version. Now with R 2.12.0 alpha
the package builds [Windows XP] but it still fails when checking:

---
C:\home\javier\Documents\hydrology\development>R CMD check hydrosim
* using log directory
'C:/home/javier/Documents/hydrology/development/hydrosim.Rcheck'
* using R version 2.12.0 alpha (2010-09-28 r53056)
* using platform: i386-pc-mingw32 (32-bit)
* using session charset: ISO8859-1
* checking for file 'hydrosim/DESCRIPTION' ... OK
* this is package 'hydrosim' version '1.0-0'
* checking package dependencies ... OK
* checking if this is a source package ... OK
Error in system2("file", "--version", TRUE, TRUE) : '"file"' not found
Execution halted

C:\home\javier\Documents\hydrology\development>file
"file" no se reconoce como un comando interno o externo,
programa o archivo por lotes ejecutable.

As you may guess, the above means "'file' is not recognized as an internal
or external command, operable program or batch file".

Could you help with this? Perhaps the string "file" should have been
substituted by a file name elsewhere before? Could the white spaces in
"C:\Archivos de programa\..." be the source of the problem?

Thanks again,

Javier

Hi,

I am working on a package with several hydrological functions which
builds/checks/INSTALLs gracefully for a Linux box. However, for a
Microsoft Windows XP [Versi?n 5.1.2600] I have the error:

C:\Archivos de programa\R\R-2.9.2\bin>R CMD build
C:\home\javier\Documents\hydrology\development\hydrosim

Are you really using version 2.9.2?  If so, I think you're on your own.
The current release is 2.11.1, and our efforts are concentrated on
testing the alpha/beta of 2.12.0 now.

Can't locate R/Dcf.pm in @INC (@INC contains: C

However, the content of the first mentioned folder is:

C:\ARCHIV~1\R\R-29~1.2\share\perl\R>ls
Dcf.pm Logfile.pm Rd.pm Rdconv.pm Rdlist.pm Rdtools.pm Utils.pm Vars.pm

Is there a problem with the way windows abbreviates folder names for
long
names of names withs spaces? Or the problem is elsewhere?

Please, could you help?

Thanks and best regards,
