[R] Question about coplot() ...

[C. Joseph Lu]

Thanks kind suggestions from Bendix Carstensen and Emmanuel Paradis
for my question about coplot():

> >> coplot(y ~ x|i, data=xy)
> >coplot gives 3 panels, rather than 2, namely one for i=1 and one for
> >i=2.
> Try:
>         coplot(y ~ x|factor(i), data=xy)

Actually, my question is on:

    Is this appropriate (with default settings of coplot)?
                       ^^^^^^^^^^^^^^^^^
which is the last sentence on my question.

Best regards,
