dots: Create a quick dotchart (histogram)

In TeachingDemos: Demonstrations for Teaching and Learning

Create a quick dotchart (histogram)

Description

Create a quick dotchart of 1 or 2 datasets. These dotcharts are a poor man's histogram, not the trellis dotplot.

Usage

dots(x,...)
dots2(x, y, colx = "green", coly = "blue", lab1 =
deparse(substitute(x)), lab2 = deparse(substitute(y)),...)

Arguments

x	Vector, data to be plotted (should be rounded).
y	Vector, second dataset to be plotted.
colx	Color of points for x.
coly	Color of points for y.
lab1	Label for x.
lab2	Label for y.
...	Additional arguments passed to plotting functions.

Details

These functions create basic dotcharts that are quick "back of the envelope" approximations to histograms. Mainly intended for demonstration.

Value

No meaninful value. These functions are run for the side effect of creating a plot.
