Discrepancies in the estimates of Partial least square (PLS) in SAS and R

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

That is documented in the help pages:

library(pls)
?plsr

[snip]
   scale: numeric vector, or logical.  If numeric vector, X is scaled
          by dividing each variable with the corresponding element of
          'scale'.  If 'scale' is 'TRUE', X is scaled by dividing each
          variable by its sample standard deviation.  If
          cross-validation is selected, scaling by the standard
          deviation is done for every segment.

When in doubt, read the documentation. :)
