CRdraw_lines | R Documentation |
Draws multiple lines defined in line_list to rendering target. Line_list contains vector elements x1, y1, x2, y2, with each set (x1[i], y1[i], x2[i], y2[i]) defining one line. Consecutive lines are connected at the ends, i.e. a line is drawn from (x2[i], y2[i]) to (x1[i+1], y1[i+1]).
