plot: Generic X-Y Plotting

Description

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

Usage

plot(x, y, ...)

Arguments

x

the coordinates of points in the plot. Alternatively, a single plotting structure, function or any Robject with a plot method can be provided.

y

the y coordinates of points in the plot, optional if x is an appropriate structure.

...

graphical parameters can be given as arguments to plot. Many methods will also accept the following arguments:

type{what type of plot should be drawn. Possible types are

• "p"for

Details

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

The two step types differ in their x-y preference: Going from $(x1,y1)$ to $(x2,y2)$ with $x1 < x2$, type = "s" moves first horizontal, then vertical, whereas type = "S" moves the other way around.

Examples

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)")

## Simple quantiles/ECDF, see ecdf() {library(stats)} for a better one:
plot(x <- sort(rnorm(47)), type = "s", main = "plot(x, type = "s")")
points(x, cex = .5, col = "dark red")
