| \title{Basic Internal Plot Function} |
| \description{ |
| This is \emph{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"), \dots) |
| } |
| \arguments{ |
| \item{xy}{A four-element list as results from |
| \code{\link{xy.coords}}.} |
| \item{type}{1 character code: see \code{\link{plot.default}}. |
| \code{NULL} is accepted as a synonym for \code{"p"}.} |
| \item{pch}{character or integer code for kind of points, see |
| \code{\link{points.default}}.} |
| \item{lty}{line type code, see \code{\link{lines}}.} |
| \item{col}{color code or name, see \code{\link{colors}}, |
| \code{\link{palette}}. Here \code{NULL} means colour 0.} |
| \item{bg}{background (fill) color for the open plot symbols 21:25: |
| see \code{\link{points.default}}.} |
| \item{cex}{character expansion.} |
| \item{lwd}{line width, also used for (non-filled) plot symbols, see |
| \code{\link{lines}} and \code{\link{points}}.} |
| \item{\dots}{further \link{graphical parameters} such as \code{xpd}, |
| \code{lend}, \code{ljoin} and \code{lmitre}.} |
| } |
| \details{ |
| The arguments \code{pch}, \code{col}, \code{bg}, \code{cex}, |
| \code{lwd} may be vectors and may be recycled, depending on |
| \code{type}: see \code{\link{points}} and \code{\link{lines}} for |
| specifics. In particular note that \code{lwd} is treated as a vector |
| for points and as a single (first) value for lines. |
| |
| \code{cex} is a numeric factor in addition to \code{par("cex")} which |
| affects symbols and characters as drawn by \code{type} \code{"p"}, |
| \code{"o"}, \code{"b"} and \code{"c"}. |
