ash_1d: Average shifted histogram.

In hadley/densityvis: Common interface to a range of density calculations.

Description

Average shifted histogram.

Usage

ash_1d(x, weight, binwidth, bins=20, m=5, na.rm=FALSE,
    range)

Arguments

x	a numeric vector of positions
weight	NULL or a numeric vector providing weights for each observation
bins	desired number of bins
binwidth	desired bin width (specify this or bins)
na.rm	If TRUE missing values will be silently removed, otherwise they will be removed with a warning.
m	smoothing parameter - this many different starting origins between min(range) and min(range) - binwidth will be generated.
range	range of values to use, if different to range of data.

Details

Computes bins for m evenly spaced origins, then averages the counts over those bins.

Value

A data frame with three columns:

left	the left end of the interval
right	the right end of the interval
count	the number of observations in that interval

Examples

x <- ash_1d(runif(100))
# Simple plot methoded included in package
plot(x)

plot(ash_1d(baseball$b, m = 10))
plot(ash_1d(baseball$b, bins = 100))
