You probably want to read the Introduction to R that comes with R
(menu: Help>Manuals (in PDF)>Introduction to R).

If you have an function, f, and you type just 'f', then R prints the function,
just as it does for any other object.
  > z <- function(x)
  + {
  +     if (missing(x)) "<missing x>" else x + 100
  + }
  > z
  function (x)
  {
      if (missing(x)) "<missing x>" else x + 100
  }
If you want to evaluate a function you must supply the arguments in
parentheses (even if there are no arguments you need the parentheses).
  > z(10:12)
  [1] 110 111 112
  > z()
  [1] "<missing x>"

Hi Bill,
I start with a > prompt
I type the command in the syntax that appears to be correct
I immediately get a > prompt back
I type getwd and get no indication of any directory at all just the following:
> getwd
function ()
.Internal(getwd())
<bytecode: 0x000000000cb0df80>
<environment: namespace:base>

Does "nothing happens" mean that R does not even print "> ", prompting you
to enter more input?

Did you get such a prompt before typing setwd("...")?

What does typing
   5:2
cause R to do?
