\title{
Plotting Two y-Axes
}
\description{
Line plot with y-axes on both left and right side.
}
\usage{
plotyy(x1, y1, x2, y2, gridp = TRUE, box.col = "grey",
type = "l", lwd = 1, lty = 1,
xlab = "x", ylab = "y", main = "",
col.y1 = "navy", col.y2 = "maroon", ...)
}
\arguments{
\item{x1, x2}{x-coordinates for the curves}
\item{y1, y2}{the y-values, with ordinates y1 left, y2 right.}
\item{gridp}{logical; shall a grid be plotted.}
\item{box.col}{color of surrounding box.}
\item{type}{type of the curves, line or points (for both data).}
\item{lwd}{line width (for both data).}
\item{lty}{line type (for both data).}
\item{xlab, ylab}{text below and on the left.}
\item{main}{main title of the plot.}
\item{col.y1, col.y2}{colors to be used for the lines or points.}
\item{...}{additional plotting parameters.}
}
\details{
Plots \code{y1} versus \code{x1} with y-axis labeling on the left and plots
\code{y2} versus \code{x2} with y-axis labeling on the right.
The x-values should not be too far appart. To exclude certain points, use
\code{NA} values. Both curves will be line or point plots, and have the
same line type and width.
}
\value{
Generates a graph, no return values.
