| segments {base} | R Documentation |
Draw line segments between pairs of points.
segments(x0, y0, x1, y1,
col = par("fg"), lty = par("lty"), xpd = FALSE)
x0,y0 |
coordinates of points from which to draw. |
x1,y1 |
coordinates of points to which to draw. |
length |
length of the edges of the arrow head (in inches). |
angle |
angle from the shaft of the arrow to the edge of the arrow head. |
col, lty, xpd |
usual graphical parameters as in par. |
For each i, a line segment is drawn between the point (x0[i],
y0[i]) and the point (x1[i],y1[i]).
The graphical parameters col and lty can be used
to specify a color and line texture for the line segments (col
may be a vector).
arrows,
polygon for slightly easier and less flexible line drawing and
lines for the usual polygons.
