[R] calculation of U and V matrix of SVD decomposition (according to LINPACK, X = UDV')
Hello, Like QR decomposition, I am looking for decomposition to get U and V matrix of SVD decomposition (according to LINPACK, X = UDV'). Do you know if there is a function which could calculate this decomposition? Look forward to your reply, Haleh

It may really make much sense for you to learn how to get help from R's builtin documentation systems. Probably you should also take time to read the "Introduction to R" manual that is almost surely part of your R installation, and is additionally available from the R project web pages. >>>> PLEASE do read the posting guide! >>>> http://www.R-project.org/posting-guide.html Regards, Martin Maechler
