R help - Dec 2006 - Weighted averaging partial least squares regression

Hello, 

is it possible in R to calculate a Weighted averaging partial least
squares regression? I'm not firm in statistics and didn't found anything
about weighted averaging in combination with PLS in the help archives.
Or is it possible to develop a workaround with the pls-package?

thanks for help in advance
Andreas Plank

Nothing in R that is publicly available. It is certainly possible to 
modify the
pls package (I did so for package cocorresp, but that does something slightly
different to what you want).

Steve Juggins is writing an R package that includes WA-PLS, you might wish to
contact him to see if there is an early version available that you might use.
His University web pages are here:

And you'll find his email address on them.
