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"),
...
)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 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)
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)
