Hi, According to the help file for model.frame/get_all_vars, the following should produce the same output from both functions, but it doesn't...
> dat <- list(X=matrix(1:15,5,3),z=26:30) > model.frame(~z+X,dat) z X.1 X.2 X.3 1 26 1 6 11 2 27 2 7 12 3 28 3 8 13 4 29 4 9 14 5 30 5 10 15 > get_all_vars(~z+X,dat) [1] z X <NA> <NA> <0 rows> (or 0-length row.names) > -- the equivalent works ok if there are no matrices involved. I'm using R version 2.9.0 alpha (2009-03-24 r48212) (Suse linux 10 and 11, 64 bit intel). I found the problem while trying to fix a problem in an mgcv plotting routine. best, Simon -- > Simon Wood, Mathematical Sciences, University of Bath, Bath, BA2 7AY UK > +44 1225 386603 www.maths.bath.ac.uk/~sw283 ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
