plot.xy {graphics}
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 = par("pch"), lty = par("lty"),
col = par("col"), bg = NA,
cex = 1, lwd = par("lwd"), ...)
Arguments
- xy
- A four-element list as results from
xy.coords. - type
- 1 character code: see
plot.default.NULLis accepted as a synonym for"p". - pch
- character or integer code for kind of points, see
points.default. - lty
- line type code, see
lines. - col
- color code or name, see
colors,palette. HereNULLmeans colour 0. - bg
- background (fill) color for the open plot symbols 21:25: see
points.default. - cex
- character expansion.
- lwd
- line width, also used for (non-filled) plot symbols, see
linesandpoints. - ...
- further graphical parameters such as
xpd,lend,ljoinandlmitre.
Details
The arguments pch, col, bg, cex, lwd may be vectors and may be recycled, depending on type: see points and lines for specifics. In particular note that lwd is treated as a vector for points and as a single (first) value for lines.
cex is a numeric factor in addition to par("cex") which affects symbols and characters as drawn by type "p", "o", "b" and "c".
