Assign values to nodePar of dendrogram's leaves

Description

Go through the dendrogram leaves and updates the values inside its nodePar

If the value has Inf then the value in edgePar will not be changed.

Usage

1
2
assign_values_to_leaves_nodePar(dend, value, nodePar,
  warn = dendextend_options("warn"), ...)

Arguments

dend

a dendrogram object

value

a new value vector for the nodePar attribute. It should be the same length as the number of leaves in the tree. If not, it will recycle the value and issue a warning.

nodePar

the value inside nodePar to adjust.

warn

logical (default from dendextend_options("warn") is FALSE). Set if warning are to be issued, it is safer to keep this at TRUE, but for keeping the noise down, the default is FALSE.

...

not used

Value

A dendrogram, after adjusting the nodePar attribute in all of its leaves,
