Assign values to edgePar of dendrogram's leaves

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

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

assign_values_to_leaves_edgePar(
  dend,
  value,
  edgePar,
  warn = dendextend_options("warn"),
  ...
)

Arguments

dend

a dendrogram object

value

a new value vector for the edgePar 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.

edgePar

the value inside edgePar 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 edgePar attribute in all of its leaves,
