dots

Create a quick dotchart (histogram)

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

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

`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.

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

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

dots( round( rnorm(50, 10,3) ) )
dots2( round( rnorm(20, 10,3) ), round(rnorm(20,12,2)) )
