See ?qr and http://ikpe1101.ikp.kfa-juelich.de/briefbook_data_analysis/node224.html
Note the compact form of how QR decomposition in R works.

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.
