Each trial is a column and the rows are organized by time.  I know there is a code to take out single outliers within a certain trial by using the chi square test code. But, I want to be able to determine if trials are outliers. I am having a tough time finding/coming up with a code that will allow this. Are there any suggestions?!

This is, to say the least, a somewhat loaded question: see, e.g., this
thread https://stat.ethz.ch/pipermail/r-help/2012-July/318746.html,
for  some thoughts.

Cheers,
Michael
