New R code for mass univariate analysis of ERP data

I've updated my R code page to include two new functions for conducting mass univariate analyses on ERP data. One function runs the statistics, and the other plots the ERP waveforms with windows of statistical significance, as determined by the mass univariate statistics, as colored bars underneath the waveforms. The mass univariate function includes a variety of possible methods that are explained in more detail in the excellent tutorial published by Groppe et al. (2011). Comments and feedback welcome!
