numeric vector of data for histogram. Missing values
(
NAs) are allowed and omitted.
OPTIONAL ARGUMENTS:
nbins
The suggested number of bins. Either a number, or a character string
naming a rule:
"Scott" or
"Freedman-Diaconis" or
"FD". (Case is ignored.)
h
The bin width (takes precedence over
nbins).
x0
Shift for the bins - the breaks are at
x0 + h * (..., -1, 0, 1, ...)
breaks
The set of breakpoints to be used. (Usually omitted, takes precedence
over
h and
nbins).
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 number for the bar fill.
xlab
label for the plot x-axis. By default, this will be the name of
data.
bty
The box type for the plot - defaults to none.
...
additional arguments to
polygon or
plot.
SIDE EFFECTS:
A histogram is plotted on the current device.
DETAILS:
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.
