[R] Running R 3.2.2 on Mac OS X 10.11.3 - not getting proper response to ls and dir commands ... launching error scripts. See below:

   > dir
   function (path = ".", pattern = NULL, all.files = FALSE, full.names =
FALSE,
       recursive = FALSE, ignore.case = FALSE, include.dirs = FALSE,

Note what a difference the parentheses after the function name make.  With
parentheses,
often with arguments in the parentheses, you call the function; without
parentheses you
get the function definition,
