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

Arguments

x	the coordinates of points in the plot. Alternatively, a single plotting structure, function 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, "c" for the lines part alone of "b", "o" for both “overplotted”, "h" for “histogram” like (or “high-density”) vertical lines, "s" for stair steps, "S" for other steps, see Details below, "n" for no plotting. All other types give a warning or an error; using, e.g., type = "punkte" being equivalent to type = "p" for S compatibility.
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.

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

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)")

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