Add Line Segments to a Plot
Draw line segments between pairs of points.
segments(x0, y0, x1 = x0, y1 = y0, col = par("fg"), lty = par("lty"), lwd = par("lwd"), …)
- x0, y0
coordinates of points from which to draw.
- x1, y1
coordinates of points to which to draw. At least one must be supplied.
- col, lty, lwd
i, a line segment is drawn between the point
(x0[i], y0[i]) and the point
(x1[i], y1[i]). The
coordinate vectors will be recycled to the length of the longest.
The graphical parameters
lwd can be
vectors of length greater than one and will be recycled if necessary.
