| cluster3 {ClassDiscovery} | R Documentation |
Produces and plots dendrograms using three similarity measures: Euclidean distance, Pearson correlation, and Manhattan distance on dichotomized data.
cluster3(data, eps = logb(1, 2), name = "", labels = dimnames(data)[[2]])
data |
A matrix, numeric data.frame, or
exprSet object. |
eps |
A numerical value; the threshold at which to dichotmoize the data |
name |
A character string to label the plots |
labels |
A vector of character strings used to label the items in the dendrograms. |
Invisibly returns the data object ojn which it was invoked.
