Hi.
When I extend "numeric" with S4 and create an instance, I get something
that looks and acts like a numeric. When I extend "data.frame" and
create an instance, I get a NULL 'core'. Why is this, and can it be
fixed? setOldClass(), prototype=, and initialize() don't seem to help.
Thanks,
Tim

setClass("numClass",representation("numeric",num="numeric"))
nn <- new("numClass",2,num=1)
nn
nn+1
setClass("dfClass",representation("data.frame",num="numeric"))
df <- new("dfClass",as.data.frame(BOD),num=1)
df
