compNorm
(Package: nnNorm) :
Compares the distribution of several vectors at a time using either boxplots or density curves
This function was concieved to easily compare several normalization methods in terms of variability of log-ratios, M. Basically it produces two plots: The first is a the density plot of the several matrices passed as arguments, while the second is a box plot. Median of absolute deviations for each method is printed on screen.
