[R] R CMD build creates tar file instead of tar.gz file

[Ian Schiller]

Dear all,

I'm trying to create my own package by following for instance http://epub.ub.uni-muenchen.de/6175/2/tr036.pdf  In step 6 (page 19) it says that the command 'R CMD build <mypackage>' should result in a tar.gz file.  However, after running the command I end up with a tar file only (no gz extension).  I also get the following warnings in the command prompt

C:\Program Files\R\R-2.12.2\src>R CMD build HSROC
* checking for file 'HSROC/DESCRIPTION' ... OK
* preparing 'HSROC':
* checking DESCRIPTION meta-information ... OK

I have installed R-2.12.2 which should be the latest version.  I also have the latest version of Rtools (Rtools212.exe).  My operating system is Windows XP professional x64 edition if it can help.  Any clues on how to solve this issue would be appreciated.

Ian
