[R] nnet trouble

[Sirotkin, Alexander]

Hi.

I've spent a few days trying to use nnet package on a data other
that the example iris3 without any success.

I keep getting

Error in matrix(NA, length(keep), nout, dimnames = list(rn, 
dimnames(object$fitted)[[2]])) :
        length of dimnames[1] not equal to array extent

in predict() function on a data that looks absolutely similar to the 
example (except for
actual values and field names, of course).

Any1 can suggest anything I can try ? Is the package supposed to work at 
all ?
