ahist: Histogram using active bins

In extracat: Categorical Data Analysis and Visualization

Description

A standard histogram using getbw to compute the binwidth and breakpoints.

Usage

ahist(x, k = NULL, m = NULL, fun = "qplot", col = "grey", ival = NULL)

Arguments

x	A numeric vector.
k	The desired number of active bins. A bin is active if it contains at least min_n observations. The default is k <- 1 + 2*ceiling(log(N)/log(2)).
m	The minimum number of observations necessary for a bin to count as an active bin. Defaults to m = max(log(N/10)/log(10),1).
fun	Either "qplot" or "hist".
col	The color for the bars.
ival	If this is set to a numeric value in (0,1) then x is trimmed according to innerval(x, p = ival).

Value

The ggplot object.

Note

This is purely experimental at this time.

ahist(x)


x <- c(rnorm(400),rnorm(200, mean=32))
ahist(x)

## End(Not run)
