Description

This is the internal function that does the basic plotting of points and lines. Usually, one should rather use the higher level functions instead and refer to their help pages for explanation of the arguments.

Usage

plot.xy(xy, type, pch = 1, lty = "solid", col = par("fg"), bg = NA,
        cex = 1, lwd = par("lwd"), ...)

Arguments

xy

A four-element list as results from xy.coords.

type

1 character code.

...

further graphical parameters.

The arguments pch, col, bg, cex, lwd are may be vectors and recycled, depending on type, see points and lines for specifics.

Examples

points.default # to see how it calls "plot.xy(xy.coords(x, y), ...)"
