R-list --
I am working with some SPlus code and get the following error
Error in terms.default(formula, data = data) :
no terms component
Can someone point me to a fix? The pasted formula looks ok
when printed during the procedure.
Thanks,
Dan

R and S-PLUS handle terms very differently. If this were a formula, terms would dispatch to term.formula, so presumably it is not. Do you need an as.formula() call? On Thu, 6 Mar 2003, Daniel A.

It looks a little like the terms.default method has been called directly rather than via the generic terms function. This is generally a bad idea. -- Ross Ihaka Email: ihaka at stat.auckland.ac.nz Department of Statistics Phone: (64-9) 373-7599 x 85054 University of Auckland Fax: (64-9) 373-7018 Private Bag 92019, Auckland New Zealand
