Determine if a function is an S3 generic or S3 method.
is_s3_generic compares name to .knownS3Generics and
.S3PrimitiveGenerics, then looks at the function body to see if it
calls UseMethod().
is_s3_method builds names of all possible generics for that function
and then checks if any of them actually is a generic.
is_s3_generic(name, env = parent.frame()) is_s3_method(name, env = parent.frame())
name |
Name of function. |
env |
Base environment in which to look for function definition. |
