I think what you are referring to is already nicely i

thank you John, as always, for your thoughtful responses. (i've been
teaching my children to play chess, which probably isn't that
different an experience ;) one further comment and a related (maybe)
bug report.

I wish I were a more knowledgeable computer weenie, but I'm just an amateur

Since I could install R easily from CRAN but the packages balked with the
default security settings but installed without incident when I turned the

IMO, the recommended version is:
setClass("kid2", contains = c("mom", "VIRTUAL"))
because it's the clearest, using the representation argument only for
defining slots. Better yet, if your virtual classes don't have any
slots defined, use setClassUnion() for "mom", with the other classes

You're conflating 3 different things here: how methods are selected,
how R treats missing arguments, and how the standardGeneric() call is
implemented.
Maybe more relevant, if this question is motivated by a practical need,
you may want to rethink what the generic function does. "Nonstandard"

Why would you want to do that? Does that model have some particular
synergy with R's design or curre

What Luis probably means can be reproduced by this little example:
a<-5:1
b<-t(t(a))
b
sort(b)
In R 2.2.1 (Windows XP), sort(b) is a matrix with 1 column, like b. In R 2.4.0
(and presumably already 2.3.1), sort(b) is no longer a matrix but a vector (and
displayed as a row).

Thanks for the report.
It would be interesting to know if the package installation fails
because of chm files or because you are trying to install stuff into a
directory with insufficient permissions even for other files.
If we are supposed packages in a different way for Vist
