[R] what.is(object)

hi:  still experimenting.  is there a function that tells me what an S 
object is, or how it is constructed?

s <- cor.test ( x, y );

s$estimate$name = 'correlation' ;   <-  try to rename 'cor' to 
'correlation' fails.  obviously, name is not a part here.
s$newfield = c("another info field", 3.2 ) ;  <- this is not congruous


what.is(s)       #tells me that this is a class called htest
what.is(s$statistic)    # helps me

would allow me to see how things are constructed.   does S contain such 
a feature?
