First, it is not a function. It is an R object in the stats namespace
and you can look at it like any other object:
DLL name: stats
Dynamic lookup: FALSE
 "CallRoutine" "NativeSymbolInfo"
That tells you it is invoking a C function called Cdqrls: you can search
from that in the sources for package stats. In fact it is in
You would know to look in the stats namespace since you found this in a
function from that namespace.
Generally R's own code uses the convention of object C_foo for C entry
point foo and F_bar for Fortran entry point bar (but there are
exceptions, more so in R < 3.0.0).
