R: Assign values to nodePar of dendrogram's leaves

assign_values_to_leaves_nodePar {dendextend}

R Documentation

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

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,

Examples


## Not run: 

dend <- USArrests[1:5,] %>% dist %>% hclust("ave") %>% as.dendrogram

# reproduces "labels_colors<-" 
# although it does force us to run through the tree twice, 
# hence "labels_colors<-" is better...
plot(dend)
dend <- assign_values_to_leaves_nodePar(dend=dend, value = c(3,2), nodePar = "lab.col")
plot(dend)

dend <- assign_values_to_leaves_nodePar(dend, 1, "pch")
plot(dend)
# fix the annoying pch=1:
dend <- assign_values_to_leaves_nodePar(dend, NA, "pch")
plot(dend)
# adjust the cex:
dend <- assign_values_to_leaves_nodePar(dend, 19, "pch")
dend <- assign_values_to_leaves_nodePar(dend, 2, "lab.cex")
plot(dend)

str(unclass(dend))

get_leaves_attr(dend, "nodePar", simplify=FALSE)
