truehist.RdCreates 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. |

A histogram is plotted on the current device.
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.
