It's certainly there! we all mirror it from Vienna !
It maybe that the html text doesn't yet have the proper link...
But it IS there (and on any other CRAN mirror)
 in the   ./src/base/ directory !

Certainly --- if you enhance it;
Thanks in advance for the contribution...  ;-)

kronecker() is actually a wrapper for outer(), so unfortunately you will
have to enhance outer() as well!  But I expect an enhanced outer() would
be quite useful.

Cheers, Jonathan.
