[R] gumbel distribution

Having acquired some evidence that I am not *totally* confused, let me 
suggest to Ms. Botto that she have a look at the FAdist package which 
appears to provide [dpqr]gumbel() with the usual sort of syntax.  There 
is also an implementation of the Gumbel distribution in the VGAM package.

RSiteSearch("Gumbel") turns up lots of hits.

cheers,

Rolf Turner
