k-means cluster and plot labels
Try the pch() argument to plot(), or perhaps using text(), depending on what exactly you're trying to achieve. Sarah

Hi, For my data, I followed the example of http://en.wikibooks.org/wiki/Data_Mining_Algorithms_In_R/Clustering/K-Means#Execution and got some very nice results. 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? Any pointer is appreciated. TIA Christian
