Try the pch() argument to plot(), or perhaps using text(), depending
on what exactly you're trying to achieve.

Despite the fact, that I want to achieve a bit more by clustering my data (stratification beyond case-control), the actual data-frame contains a column labeled "C" which holds a case-control indicator (here either "Z" for the trait and "C" for control or alternatively "1" vs. "0"). Is there a way to display this status character in the plot?
