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) Method #1 produces a crosshair with fat lines. It is not possible to adequately scale the "plus-sign" for my purposes, due to messages like: X11 used font size 34 when 42 was requested Method #2 produces a thin crosshair, but it is difficult to get the two crosshair lines to be of the same physical length on the device. the lines also change length when i change/resize the device.
