R help - May 2012 - Discrepancies in the estimates of Partial least square (PLS) in SAS and R

I have been using R and SAS from past 6 months and i found a interesting
thing while doing PLS in R and SAS is that when we use NO SCALE option in
SAS and scale=FALSE in R , we see the estimates are matching but if we use
scaling option in SAS and R the estimates differ to greater extent , you can
try with any data set we will get very different estimates while using the
scaling option. can any one help me in this issue ?

My guess is that they use different scalings, which of course will give
different results.  However, since you don't say anything about which R
package you use for PLSR (and since I don't have access to SAS), I can
only guess. :)

I am using pls package but how is scaling done in R?
