.Primitive looks up by name a ‘primitive’ (internally implemented) function.
- name of the R function.
The advantage of
.Internal functions is the potential efficiency of argument passing, and that positional matching can be used where desirable, e.g. in
switch. For more details, see the ‘R Internals Manual’.
All primitive functions are in the base namespace.
This function is almost never used:
`name` or, more carefully,
get(name, envir = baseenv()) work equally well and do not depend on knowing which functions are primitive (which does change as R evolves).
Prior to R 2.14.2 this could also be used to retrieve
.Internal functions: this was unintentional.
