ftype {sloop} | R Documentation |
Determine function type.
Description
This function figures out whether the input function is a regular/primitive/internal function, a internal/S3/S4 generic, or a S3/S4/RC method. This is function is slightly simplified as it's possible for a method from one class to be a generic for another class, but that seems like such a bad idea that hopefully no one has done it.
Usage
ftype(f)
Arguments
f |
unquoted function name |
Value
a character of vector of length 1 or 2.
Examples
ftype(`%in%`)
ftype(sum)
ftype(t.data.frame)
ftype(t.test) # Tricky!
ftype(writeLines)
ftype(unlist)
