R help - Sep 2003 - Gram-Schmidt orthonormal factorization

Hi:

Does R have a function as gsorth is SAS, that perform a the Gram-Schmidt
orthonormal factorization of the m ?n matrix A, where m is greater than or
equal to n? That is, the GSORTH subroutine in SAS computes the
column-orthonormal m ?n matrix P and the upper triangular n ?n matrix T such
that A = P*T.

or any other version of Gram-Schmidt orthonormal factorization?

I search the help, but I didn?t find any thing about.

Thanks, Gabriela

PD: I am using R 1.7.1, for Windows 98.

See ?qr
and

Note the compact form of how QR decomposition in R works.
