sis_discretize: Discretize continuous trait data

In bomeara/sisters: Runs various sister group comparisons to test hypotheses about diversification

Discretize continuous trait data

Description

Converts a vector of numbers into a vector of 0 and 1 based on whether they are below or above some value. There are two ways to do this: based on percentile or based on a numeric cutoff. By default, it will separate it based on the 50th percentile (cutoff of 0.5), but you can change the cutoff value and whether it is used as percentile or trait value.

Usage

sis_discretize(x, cutoff = 0.5, use_percentile = TRUE)

Arguments

x	Vector of continuous trait values
cutoff	Value to use as cutoff. If percentile, 0.3 = 30th percentile, etc.
use_percentile	If TRUE, use cutoff as percentile

Value

a vector of 0 and 1 (and NAs)
