Hierarchical clustering on an spectral counts matrix.
Hierarchical clustering of samples in an spectral counts matrix, coloring tree branches according to factor levels.
A MSnSet with spectral counts in the expression matrix.
A logical indicating whether to plot the dendrograms.
NULL, or a data frame with factors. See details below.
This function may draw different plots, one by given factor in
The hierarchical clustering is done by means of
hclust with default parameters.
do.plot is TRUE, a dendrogram is plotted for each factor, with branches colored as per factor level. If
facs is NULL then the factors are taken
Invisibly returns the the value obtained from
