I promised a post with heatmaps, and I delivered more with PCA, MDS and clustering

I am back from the 1st summer Institute in statistics for big data held in the university of Washington. I have learned so much!

I wrote up a short tutorial for

PCA, MDS, k-means, Hierarchical clustering and heatmap for microarray data

and put it on Rpubs.

Happy learning!
