| colorplot {labeltodendro} | R Documentation |
The dendrogram is cut at the appropriate value, defined in a labclust object, and leaves are coloured repectively.
colorplot(x,h,horiz=FALSE,...)
x |
A labclust object to be plotted. |
h |
The height that the tree should be cut, automatically extracted from a labclust object. |
horiz |
Clarifies to plot the dendrogram horizontally or vertically. |
... |
Some of dendrogram plot options, but not all. |
The colorplot function is a modified version of HeatPlus package to cut a dendrogram and colour its leaves. Leaves with single element won't be coloured.
x<-matrix(c(

plot(labeltodendro(x),horiz=TRUE) # changes orientation and dendrogram height starts from zero
