Is 'newframe' a matrix or a dataframe?
If it is a dataframe, try:
names(newframe) <- colnames(tailmatrix)
predict(fit, newframe)
-roger

Hello,
can someone give me an example of how to fit a linear model where the
response is a matrix, please? (other than a loop over lm calls)
The ?lm points me to model.matrix but it is not clear to me how to use a
model matrix in an lm call.
fit<-lm(headmatrix ~ tailmatrix) causes problems as soon as I
use predict(fit,newframe). The variables in tailmatrix are not found in
newframe.
Thanks,
Claus
