I am trying to install package RODBC via CRAN on MacBook Air with OS 10.12.
I am receiving the below error:
Installing package into ‘/Users/aaron.samuels/Library/R/3.3/library’
(as ‘lib’ is unspecified)
Package which is only available in source form, and may need compilation of
C/C++/Fortran: ‘RODBC’
Do you want to attempt to install these from sources?

Any suggestion on how I can easily install these headers and subsequently successfully install RODBC?
