This function can be used to graphically demonstrate the relationship between distribution shape, an idealized normal distribution (based on sample mean and sd) shape, and measures of central tendency / spread.

percentileDemo(x, labels.signif = 3, pctile.color = "RoyalBlue",
mean.color = "Orange", range.color = "DarkRed",
hist.breaks = 30, boxp = FALSE, ...)

## Arguments

x vector of values to summarize integer, number of significant digits to be used in figure annotation color used to demonstrate range from 10th to 90th percentiles color used to specify mean +/- 2SD color used to specify data range integer, number of suggested breaks to hist logical, add a box and whisker plot? further arguments to plot

## Value

A 1-row matrix of summary stats is invisibly returned.
