dotsplot.rgb: Color-ramp scatterplot

In mbtyers/MTfuncs: What the package does (short line)

Description

Creates a 2-d scatterplot with a third variable plotted on a color ramp

Usage

dotsplot.rgb(x, y, z, ramp = "gr", pch = 16, add = F, legend = T,
  cex = 1, neut = 0.5, legend.title = NULL, invert = F, xlab = "",
  ylab = "", main = "", ...)

Arguments

x	X-coordinate vector
y	Y-coordinate vector
z	vector of values to use for the color ramp
ramp	Type of color ramp to use, essentially possible ramps from red, green, and blue. Possible values are "gr" (default), "rg", "gb", "bg", "br", "rb", "r", "g", "b", "rr", "gg", "bb"
pch	Point character to use (defaults to 16, or solid circles)
add	A value of TRUE adds the points to an active plot, rather than creating a new one
legend	A value of FALSE suppresses the legend
cex	Universal character expansion factor for plotting (between 0 and 1)
neut	An RGB value (between 0 and 1) for the neutral color(s), those not used on the rgb ramp. It might take a little twiddling.
legend.title	Title for the legend
invert	A value of TRUE inverts the current color ramp
...	xlab, ylab, and main work like usual

Examples

x <- rnorm(1000)
y <- rnorm(1000)
z <- x+y
dotsplot.rgb(x,y,z,ramp="rg",legend.title="Legend Title")
dotsplot.rgb(x,y,z,ramp="rg",cex=.6,legend.title="Legend Title",invert=T)
