isS3stdGen Check if a Function Acts as an S3 GenericDetermines whether f acts as a standard S3-style generic function.
isS3stdGeneric(f)
f | a function object |
A closure is considered a standard S3 generic if the first expression in its body calls UseMethod. Functions which perform operations before calling UseMethod will not be considered “standard” S3 generics.
If f is currently being traced, i.e., inheriting from class "traceable", the definition of the original untraced version of the function is used instead.
If f is an S3 generic, a logical containing TRUE with the name of the S3 generic (the string passed to UseMethod). Otherwise, FALSE (unnamed).
