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

Thanks for your prompt answer Mr. Ripley.  It appears the version of tar I'm using is exactly the same as the one included in the latest Rtools.  I noticed that the Rtools/bin directory was not first in path, so I corrected this.  However, I'm still not able to create a tar.gz file with the R CMD build command.   Then my question would be the following.  If I submit my package to CRAN do you know if it needs to be tar.gz or will a tar file be accepted?

Thanks again

Ian

I think that might mean you are running the wrong version of tar.  Did 
you put the Rtools/bin directory first in your path?  What does

tar --version

give?  The current Rtools version says

tar (GNU tar) 1.21

but Cygwin is distributing a newer one.

I do see some oddities with build in 2.12.2 in Windows 7:  on my first 
attempt,  I got all sorts of errors, e.g.

* checking for file 'ellipse/DESCRIPTION' ... OK
* preparing 'ellipse':
* checking DESCRIPTION meta-information ... OK
/cygdrive/c/Rtools/bin/tar: ellipse/.svn/prop-base: file changed as we 
read it
/cygdrive/c/Rtools/bin/tar: ellipse/.svn/text-base: file changed as we 
read it
/cygdrive/c/Rtools/bin/tar: ellipse/.svn/tmp: file changed as we read it
/cygdrive/c/Rtools/bin/tar: ellipse/.svn: file changed as we read it
/cygdrive/c/Rtools/bin/tar: ellipse/chm: file changed as we read it
...

but on the second attempt it was fine.  This may be an interaction with 
a virus checker; that's often a problem on Windows.
