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)
