Library: graphic
See also: dispbox plotdot

Quantlet: dispdot
Description: Generates a dotplot with tonal highlighting. An optional factor allows multiple dotplots by group.

Usage: dp = dispdot(x , inColorScheme {, inFactor})
Input:
x n x 1 vector (continuous variable)
inColorScheme m x 3 vector (discrete) of rgb colors for the different highlighting stages
inFactor n x 1 vector (discrete variable)
Output:
dp composed graphical object

Note:

Example:
library("graphic")
library("stats")
x = normal(4000)
m = matrix(1000)
factor = m | 2*m | 3*m | 4*m
bp1 = dispdot(x, grcolorscheme("greyscale"))
bp2 = dispdot(x, grcolorscheme("topographic"), factor)
dd = createdisplay(1, 2)
show(dd, 1, 1, bp1)
show(dd, 1, 2, bp2)

Result:
Shows a dotplot of x on the left. On the right four
dotplots of the four groups within x defined by factor are
shown.
