ldahist {MASS} | R Documentation |
Plot histograms or density plots of data on a single Fisher linear discriminant.
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=if(is.trellis()) trellis.par.get("bar.fill")$col else 2, xlab=deparse(substitute(data)), bty="n", ...)
data |
vector of data. Missing values (NA s) 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 .
|
None.
Histogram and/or density plots are plotted on the current device.
