Assign values to nodePar of dendrogram's nodes

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

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

assign_values_to_nodes_nodePar(
  dend,
  value,
  nodePar = c("pch", "cex", "col", "xpd", "bg"),
  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 nodes in the tree. If not, it will recycle the value and issue a warning.

nodePar

the value inside nodePar to adjust. This may contain components named pch, cex, col, xpd, and/or bg.

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 nodes,

Examples

if (FALSE) {

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)
dend2 <- dend %>%
  assign_values_to_nodes_nodePar(value = 19, nodePar = "pch") %>%
  assign_values_to_nodes_nodePar(value = c(1, 2), nodePar = "cex") %>%
  assign_values_to_nodes_nodePar(value = c(2, 1), nodePar = "col")
plot(dend2)


### Making sure this works for NA with character.
dend %>%
  assign_values_to_nodes_nodePar(value = 19, nodePar = "pch") %>%
  assign_values_to_nodes_nodePar(value = c("red", NA), nodePar = "col") -> dend2
plot(dend2)
}
