Try using the numerical pch symbols. '3' is a crosshair, so see what
the following do:
plot(1:10,pch=3)
plot(1:10,pch=3,cex=
In a plot on an X11 device, I'd like to mark a few points with
a large thin "crosshairs". By "mark" I mean: draw the crosshair
on the plot.
The two unsatisfactory methods that I have are:
METHOD 1:
points( x, y, pch="+" ,cex=2)
METHOD 2:
line(xa, xb, y0, y0)
line(x0, x0, ya, yb)
