Hi..

    I pass a lm() object to step() but after a few steps it stops with the error message.

say:

x1<-lm(y~.,data=z)

x2<-step(x1)

i have 516 observations and 299 variables.

after a few steps i get the error message:
          Error in one %*% x : requires numeric matrix/vector arguments


anyone knows why this happens after some steps. its an lm object that is passed so i am not sure where the error might be
Thanks.

Harsh
