R: Assign values to edgePar of dendrogram's branches

assign_values_to_branches_edgePar {dendextend}

R Documentation

Assign values to edgePar of dendrogram's branches

Description

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

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

Usage

assign_values_to_branches_edgePar(dend, value, edgePar, skip_leaves = FALSE,
  warn = dendextend_options("warn"), ...)

Arguments

`dend`	a dendrogram object
`value`	a new value scalar for the edgePar attribute.
`edgePar`	a character indicating the value inside edgePar to adjust. Can be either "col", "lty", or "lwd".
`skip_leaves`	logical (FALSE) - should the leaves be skipped/ignored?
`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 branches,

Examples


# This failed before - now it works fine. (thanks to Martin Maechler)
dend <- 1:2 %>% dist %>% hclust %>% as.dendrogram
dend %>% set("branches_lty", 1:2) %>%
   set("branches_col", c("topbranch_never_plots", "black", "orange")) %>% 
   plot


## Not run: 

dend <- USArrests[1:5,] %>% dist %>% hclust %>% as.dendrogram
plot(dend)
dend <- assign_values_to_branches_edgePar(dend=dend, value = 2, edgePar = "lwd")
plot(dend)
dend <- assign_values_to_branches_edgePar(dend=dend, value = 2, edgePar = "col")
plot(dend)
dend <- assign_values_to_branches_edgePar(dend=dend, value = "orange", edgePar = "col")
plot(dend)
dend2 <- assign_values_to_branches_edgePar(dend=dend, value = 2, edgePar = "lty")
plot(dend2)

dend2 %>% unclass %>% str
