ftype: Determine function type.
In pryr: Tools for Computing on the Language
ftype 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.
See Also
Other object inspection:
otype(),
sexp_type()
Examples
ftype(`%in%`)
ftype(sum)
ftype(t.data.frame)
ftype(t.test) # Tricky!
ftype(writeLines)
ftype(unlist)
