Description

Scatter plot, with variable-based point colours

Usage

colplot(
  x,
  y,
  z,
  n = 20,
  z.lim = NULL,
  breaks = NULL,
  palette = heat.colors,
  rev = TRUE,
  pch = 21,
  add = FALSE,
  ...,
  legend = FALSE,
  n.legend = 6,
  legend.pretty = TRUE,
  legend.plot = TRUE,
  legend.x,
  legend.y = NULL,
  legend.horiz = FALSE,
  legend.bg = par("bg")
)

Arguments

x	a vector of x coordinates
y	a vector of y coordinates
z	a variable for defining colours
n	an integer giving the number of colour levels, supplied to pretty
z.lim	xxx
breaks	a vector or breaks for defining color intervals; defaults to NULL, so pretty and n are used on z
palette	a function for the color palette, or colors between breaks; defaults to heat.colors
rev	logical: should the palette be reversed? Defaults to TRUE
pch	an integer giving the plotting character, supplied to plot
add	should this be added to an existing plot? Defaults to FALSE
...	other arguments passed to plot
legend	should a legend be added? Defaults to codeFALSE
n.legend	an integer giving the approximate number of legend entries; defaults to 6
legend.pretty	logical: should the legend values produced by \[base]pretty? Othewrwise they are exact. Defaults to TRUE
legend.plot	passed to legend's plot argument
legend.x	passed to legend's x argument
legend.y	passed to legend's y argument
legend.horiz	passed to legend's horiz argument
legend.bg	passed to legend's bg argument

Value

A plot

Examples

x <- runif(50)
y <- runif(50)
colplot(x, y, x * y)
colplot(x, y, x * y, legend=TRUE, legend.x="bottomleft")
colplot(x, y, x * y, legend=TRUE, legend.pretty=FALSE, n.legend=10, 
  legend.x="bottomleft", legend.horiz=TRUE)
