I couldn't find any functions to calculate number of polytomies, and related metrics.

Here's a simple function that gives four metrics on a phylo tree object:

Here's output from the gist above:

dat $trsize [1] 15

$numpolys [1] 1

$numpolysbytrsize [1] 0.06666667

$proptipsdescpoly [1] 0.2

$propnodesdich [1] 12 `
