Rows function in nlme package

Hi

The Rows function which is called from

plot.compareFits in the nlme
package

is not found.

plot(compareFits(coef(bp.model3),coef(bp.model3M)))

Error in

plot.compareFits(compareFits(coef(bp.model3),
coef(bp.model3M))) :

couldn't find function "Rows"

Can I find it elswhere? Have I missed a required

package?

[...]

After further hunting I realise  this is probably

part of the "Trellis"

package that is seem being brewed.

It does appear that Rows() is part of Trellis in
S-Plus (given that the
example for rows is a Trellis-related example),
which means that you have
probably correctly guessed why it is not in R
(because it is not in the
lattice package which we are "brewing").

Actually, lattice DOES have the Rows() function
(precisely because it is very commonly used in
Trellis code), though it is not well documented.

In fact, if you want to use (most of) the plot
functions in nlme, you would have to have grid and
lattice installed (both under development), not only
Rows().
