ChangesInBins: Counts the changes in a series of time bins

Description

Given a vector of dates for a series of time bins and another for the times when a character change occurred will return the total number of changes in each bin.

Usage

ChangesInBins(change.times, time.bins)

Arguments

change.times

A vector of ages in millions of years at which character changes are hypothesised to have occurred.

time.bins

A vector of ages in millions of years of time bin boundaries in old-to-young order.

Value

A vector giving the number of changes for each time bin. Names indicate the maximum and minimum (bottom and top) values for each time bin.

Details

Calculates the total number of evolutionary changes in a series of time bins. This is intended as an internal function for rate calculations, but could be used for other purposes (e.g., counting any point events in a series of time bins).

Examples

# NOT RUN {
# Create a random dataset of 100 changes:
change.times <- runif(100, 0, 100)

# Create time bins:
time.bins <- seq(100, 0, length.out=11)

# Get N changes for each bin:
ChangesInBins(change.times, time.bins)

# }
