Hi all, Is there an LR decomposition function in R and, if not, how can we get the non-compact representation of Q from QR decomposition? Thanks, Jeff. -- View this message in context: http://www.nabble.com/LR-Decomposition--tp18072588p18072588.html Sent from the R help mailing list archive at Nabble.com.

You can get the answers to your questions by typing ?qr and taking it from there (click on qr.Q). Search the R help first.
