dotplot.mtb: Minitab style dotplots.

In plotrix: Various Plotting Functions

Minitab style dotplots.

Description

Create a dotplot of a data vector in the sense of "dotplot" as used in the Minitab\mbox{\copyright} package.

Usage

dotplot.mtb(x, xlim = NULL, main = NULL, xlab = NULL, ylab = NULL,
            pch = 19, hist = FALSE, yaxis = FALSE, mtbstyle=TRUE)

Arguments

x	A numeric vector.
xlim	The x limits of the plot.
main	A title for the plot; defaults to blank.
xlab	A label for the x axis; defaults to blank.
ylab	A label for the y axis; defaults to blank.
pch	The plotting symbol for the dots in the plot; defaults to a solid disc.
hist	Logical scalar; should the plot be done "histogram" style, i.e. using vertical lines rather than stacks of dots?
yaxis	Logical scalar; should a y-axis be produced?
mtbstyle	Logical scalar; should the dotplot be done in the "Minitab" style? I.e. should the zero level be at the vertical midway point?

Details

The result of hist=TRUE looks less ugly than stacks of dots for very large data sets.

Value

Nothing. A plot is produced as a side effect.

Warnings

This function does something toadally different from the dotplot() (now dotchart()) function in the graphics package.

The labelling of the y-axis is device dependent.

Examples

## Not run: 
set.seed(42)
x <- rpois(100,10)
dotplot.mtb(x,main="No y-axis.")
dotplot.mtb(x,yaxis=TRUE,main="With y-axis displayed.")
dotplot.mtb(x,hist=TRUE,main="An \"h\" style plot.")
dotplot.mtb(x,xlim=c(4,16),main="With the x-axis limited.")
dotplot.mtb(x,yaxis=TRUE,mtbstyle=FALSE,main="Non-Minitab style.")
dotplot.mtb(x,yaxis=TRUE,xlab="x",ylab="count",
            main="With x and y axis labels.")

## End(Not run)
