The purpose of this function is to compute a custom tip-spacing for users who want to expand or contract the tip-spacing of the descendant taxa from a given node or nodes.
expand.clade(tree, node, factor=5)
# S3 method for expand.clade
plot(x, ...)
The function returns an object of class "expand.clade"
which consists of the (possibly re-ordered) tree and a numerical vector with the calculated tip spacing based on the expansion factor specified by the user. This object can be plotted using the S3 plot
method for the object class; or it can be plotted simplying by calling a standard plotting function on the tree & tip spacings.
