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.See Also
points, plot, and the underlying ``primitive''
