## Histograms or Density Plots of Multiple Groups

### Description

Plot histograms or density plots of data on a single Fisher linear discriminant.

### Usage

ldahist(data, g, nbins = 25, h, x0 = - h/1000, breaks,
xlim = range(breaks), ymax = 0, width,
type = c("histogram", "density", "both"),
sep = (type != "density"),
col = 5, xlab = deparse(substitute(data)), bty = "n", ...)


### Arguments

 data vector of data. Missing values (NAs) are allowed and omitted. g factor or vector giving groups, of the same length as data. nbins Suggested number of bins to cover the whole range of the data. 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). xlim The limits for the x-axis. ymax The upper limit for the y-axis. width Bandwidth for density estimates. If missing, the Sheather-Jones selector is used for each group separately. type Type of plot. sep Whether there is a separate plot for each group, or one combined plot. 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.

### Side Effects

Histogram and/or density plots are plotted on the current device.
