[Rd] link to an alias in another package

[Paul Gilbert]

In some documentation for a package I am working on I have

 >    \code{\link[stats]{varimax}}
 >    \code{\link[stats]{promax}}

The link to varimax works, but not the one to promax. Promax is an alias 
under \name{varimax}. This kind of link works within a package, but I'm 
not sure if it is suppose to work when it is a link to another package. 
Is this a known limitation or bug, or something I should explore more 
carefully?

Thanks,
Paul
