[R] code for functions in base package

If you want to see the code (function definition) just type the function
without any parenthesizes or arguments.  In this case, the dexp function
calls C code since the .Internal function is called.  To see internal C code
you have to look at the R source.

> dexp
function (x, rate = 1, log = FALSE) 
.Internal(dexp(x, 1/rate, log))
<environment: namespace:base>
