Hi,
With some help I learned how to use plsr(Y~x, 2, data=my) function in R (and build "my" from vector "Y" and matrix "x"). 

But still I have question about results interpretation. In the end I want to construct prediction function in form:
Y=a1x1+a2x2
But I do not understand how to do it. Documentation do not describe this.
Thanks for help. ;)
