assign_values_to_leaves_nodePar {dendextend} | R Documentation |
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.
assign_values_to_leaves_nodePar( dend, value, nodePar, 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 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. |

A dendrogram, after adjusting the nodePar attribute in all of its leaves,
