Add Connected Line Segments to a Plot

Usage

lines(x, ...)
lines.default(x, y=NULL, type="l", col=par("col"), ...)

Arguments

x, y coordinate vectors of points to join.
type character indicating the type of plotting; actually any of the types as in plot(..).
col color to use.
... Further graphical parameters (see par) may also be supplied as arguments, e.g., lty.

Description

lines is a generic function taking the coordinates given in the x and y vectors and joining the corresponding points with line segments. The coordinates can alternatively be passed to lines in a plotting structure (a list with x and y components), a time series, etc.

Examples

data(cars)
# draw a smooth line through a scatter plot
