Returns a ggplot2 plot object with geom_line layer plotting FPKM values over conditions faceted by k-means clustering clusters. (Euclidean). This is very crude at this point. This does not return any of the clustering information directly, but if you want it, you can retrieve it from the ggplot object returned.
Returns a matrix of 'Specificity scores' (S) defined as 1-JSD(p_g,q_i) where p_g is the Log10+1 expression profile of a gene g across all conditions j, collapsed into a probability distribution, and q_i is the unit vector of 'perfect expression' in a given condition i.
