I am looking to have slot in an S4 class definition that can take any
(S3 or S4) object. The ANY class seemed to be a good candidate, but the
is() function definition performs an S3Case test before checking if
methods:::.identC(class2, "ANY"). The result is the is() function does
not consider various S3 objects to be of class ANY.
> is(factor(), "ANY")
[1] FALSE
> is(lm(I(1:10) ~ rnorm(10)), "ANY")
[1] FALSE
> sessionInfo()
R version 2.10.0 Under development (unstable) (2009-08-05 r49073)
i386-apple-darwin9.7.0
locale:

attached base packages:

What is the recommended base "Object" class I should define my slot to
be so it can accept any object?
