Another basic thing to check on is to be sure that you have:
\usepackage{ctable}
in the .Rnw file preamble (before the \begin{document} directive).
If you have installed the full MacTeX package, you should have the Tex Live
Utility, which is used to update/install/manage TeX packages. This can be found
in Applications/TeX. Run that and you can check to see whether ctable is
installed or not. If not, you can add it there. Some more information is here:
