In JECheadle/RSOC317L: Data Sets and Supplemental Functions from David Diez's 'OpenIntro' Textbook

Description Usage Arguments Value Author(s) References See Also Examples

Add a stacked dot plot to an existing plot. The locations for the points in the dot plot are returned from the function in a list.

1	dotPlotStack(x, radius = 1, seed = 1, addDots = TRUE, ...)

`x`	A vector of numerical observations for the dot plot.
`radius`	The approximate distance that should separate each point.
`seed`	A random seed (integer). Different values will produce different variations.
`addDots`	Indicate whether the points should be added to the plot.
`...`	Additional arguments are passed to `points`.

Returns a list with a height that can be used as the upper bound of ylim for a plot, then also the x- and y-coordinates of the points in the stacked dot plot.
