character scalar of the attribute (attr) we wish to get/set from the leaves

simplify

logical. If TRUE (default), then the return vector is after using unlist on it.

Source

Heavily inspired by the code in the function labels.dendrogram, so credit should go to Martin Maechler.

Examples

# define dendrogram object to play with:
hc <- hclust(dist(USArrests[1:3, ]), "ave")
dend <- as.dendrogram(hc)

# get_leaves_attr(dend) # error :)
get_leaves_attr(dend, "label")
labels(dend, "label")
get_leaves_attr(dend, "height") # should be 0's
get_nodes_attr(dend, "height")

get_leaves_attr(dend, "nodePar")


get_leaves_attr(dend, "leaf") # should be TRUE's
get_nodes_attr(dend, "leaf") # conatins NA's


get_leaves_attr(dend, "members") # should be 1's
get_nodes_attr(dend, "members") #


get_leaves_attr(dend, "members", simplify = FALSE) # should be 1's
