| plot {graphics} | R Documentation |
Generic function for plotting of R objects. For more details about
the graphical parameter arguments, see par.
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.
plot(x, y, ...)
x |
the coordinates of points in the plot. Alternatively, a
single plotting structure, function or any R object with a

y |
the y coordinates of points in the plot, optional

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.
plot.default, plot.formula and other
methods; points, lines, par.
For thousands of points, consider using smoothScatter()
instead of plot().
For X-Y-Z plotting see contour, persp and
image.
require(stats) # for lowess, rpois, rnorm
plot(cars)
lines(lowess(cars))
plot(sin, -pi, 2*pi) # see ?plot.function
## 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")
