bin: Calculate Bin Sizes and Limits for a Vector

In metrumrg: Pharmacometric Tools for Data Preparation, Modeling, Simulation, and Reporting

Description

Given a numeric vector, calculate bin limits, place each value in a bin, and return the number of values in each bin.

Usage

bin(
	x,
	population=x,
	breaks=quantile(population,probs=probs,...),
	probs=c(0,0.25,0.5,0.75,1),
	include.lowest=TRUE,
	...
)

Arguments

x	a vector of numeric values, to be placed in bins
population	a vector of numeric values serving as the reference population for constructing bins
breaks	bin limits (boundaries) to pass to cut
include.lowest	limit qualifier to pass to cut
probs	default probabilities for calculating breaks
...	other arguments to pass to quantile and cut

Details

By default, the population used to calculate bin limits is the same as the group of values being binned. By default, inner bin limits are the quartiles of the population.

Value

A table with bin limits encoded as column names.
