Testing for a reference class object
Hi all,
I've constructed the following function to test whether or not an
object was created from a reference class:
isRefClassObject <- function(x) isS4(x) &&
is.environment(attr(x,'.xData')) &&
exists('.refClassDef',attr(x,'.xData'))
but I'm unsure if it's a complete test or if there's a better way to
test. Regardless, It would be nice to have such a function in the
method...
