R help - Nov 2011 - Generalized singular value decomposition

Hello,

I would like to perform a generalized singular value decomposition with 
R. The only possibility I found is "GSVD" that is based on
LAPACK/BLAS.
Are there other possibilities too?
If not, has anybody used LAPACK/BLAS under Windows XP? How can I install 
them? Following [1] did not help.

I hope this is the right place for my question.

Thank you very much!

Hi,

Googling for "R-help gsvd" leads to a number of interesting entries on
the mailing list. It seems that GSVD is present in the lapack version
included with R and can be called (see the mailing list entries).

Thank you for your help!

The GSVD (SVDgen) in PTAk does not perform a generalized singular value 
decomposition for 2 matrices, only for 1. I should have mentioned this - 
sorry.
Are there maybe other packages?

I have also found the last 2 links, but I look for a way to use LAPACK 
with Windows - this issue is unfortunately not addressed in these posts.

Can anyone help me with LAPACK and Windows XP? I have noticed that there 
are already 2 dlls in the R/bin folder (Rblas.dll and Rlapack.dll). But 
I still can not load the libraries. I guess that I still have to 
"install"/do something ...

I would appreciate any help!

Regards,
Oana
