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)),...)

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.

Value

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

Details

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