| plot.xy {graphics} | R Documentation |
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.
plot.xy(xy, type, pch = par("pch"), lty = par("lty"),
col = par("col"), bg = NA,
cex = 1, lwd = par("lwd"), ...)
xy |
A four-element list as results from
xy.coords. |
type |
1 character code: see plot.default.
NULL is 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. Here NULL means 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
lines and points. |
... |
further graphical parameters such as xpd,
lend, ljoin and lmitre. |
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.
