[R-SIG-Mac] Fwd: Re: [R] Package seems to be present but library don't find it

[Duncan Murdoch]

This is a message from R-help about installing a package in OSX.  The 
NAMESPACE file contains an error, but the user didn't see the error 
message when he installed from the Mac GUI.  Is R.app missing one of the 
output streams?  I see the following in the Windows Rgui:

 > install.packages("d:/temp/HelloWorld_1.0.tar.gz", type="source", 
repos=NULL)
* installing *source* package 'HelloWorld' ...

Indeed I get this error message when I install the library using R CMD 
INSTALL but not within the GUI (in MacOsX). Good to know that R CMD 
INSTALL is more verbose and permits to track bug.

Thanks a lot.

It works fine now.
