dots: 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)),...)

Value

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

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.
