Generic X-Y Plotting

Description

Generic function for plotting of R objects. For more details about the graphical parameter arguments, see par.

Usage

plot(x, ...)
plot(x, y, xlim=range(x), ylim=range(y), type="p",
        main, xlab, ylab, ...)
plot(y ~ x, ...)

Arguments

x the coordinates of points in the plot. Alternatively, a single plotting structure or any R object with a plot method can be provided.
y the y coordinates of points in the plot, optional if x is an appropriate structure.
xlim, ylim the ranges to be encompassed by the x and y axes.
type what type of plot should be drawn. Possible types are
  • "p" for points,
  • "l" for lines,
  • "b" for both,
  • "o" for both ``overplotted'',
  • "h" for ``histogram'' like vertical lines,
  • "s" for steps,
  • "S" for other steps,
  • "n" for no plotting.
main an overall title for the plot.
xlab a title for the x axis.
ylab a title for the y axis.
... graphical parameters can be given as arguments to plot.

Details

For simple scatter plots, plot.default will be used. However, there are plot methods for many R objects, including functions, data.frames, density objects, etc. Use methods(plot) and the documentation for these.

Examples

data(cars)
plot(cars)
lines(lowess(cars))

plot(sin, -pi, 2*pi)

## Discrete Distribution Plot:
plot(table(rpois(100,5)), type = "h", col = "red", lwd=10,
     main="rpois(100,lambda=5)")
