truehist {MASS} | R Documentation |
Creates a histogram on the current graphics device.
truehist(data, nbins = "Scott", h, x0 = -h/1000, breaks, prob = TRUE, xlim = range(breaks), ymax = max(est), col = "cyan", xlab = deparse(substitute(data)), bty = "n", ...)
data |
numeric vector of data for histogram. Missing values ( |
nbins |
The suggested number of bins. Either a positive integer, or a character string
naming a rule: |
h |
The bin width, a strictly positive number (takes precedence over |
x0 |
Shift for the bins - the breaks are at |
breaks |
The set of breakpoints to be used. (Usually omitted, takes precedence
over |
prob |
If true (the default) plot a true histogram. The vertical axis has a relative frequency density scale, so the product of the dimensions of any panel gives the relative frequency. Hence the total area under the histogram is 1 and it is directly comparable with most other estimates of the probability density function. If false plot the counts in the bins. |
xlim |
The limits for the x-axis. |
ymax |
The upper limit for the y-axis. |
col |
The colour for the bar fill: the default is colour 5 in the default R palette. |
xlab |
label for the plot x-axis. By default, this will be the name of |
bty |
The box type for the plot - defaults to none. |

This plots a true histogram, a density estimate of total area 1. If
breaks
is specified, those breakpoints are used. Otherwise if
h
is specified, a regular grid of bins is used with width
h
. If neither breaks
nor h
is specified,
nbins
is used to select a suitable h
.
A histogram is plotted on the current device.
