Since you don't show what commands you used, this is guesswork, but my
guess is that you used

yourmodel <- plsr(yourresponse ~ subX, data = yourdata)
R2(yourmodel, newdata = yournewdata)

and that yourdata$subX contains 501 coloumns, but yournewdata$subX only
contains 73 coloumns.  You must supply a newdata with the same number of
coloumns as in the modelling data.
