sum_distance: Sum the distance of all branches in a dendrogram
Description
This function takes a dendrogram class object as an input, and adds up all the distances of branches.
This function is called recursively to adds up the sum. In case of exponential mapping for the quantitative
mode, the sum is in the exponential scale
Usage
sum_distance(d, sum = 0, mapping = c("exponential", "linear"), scale = 0, max_height = 0, ...)
Arguments
mapping
in case of quantitative mode, either "linear" or "exponential" mapping
Value
the sum of distances
