I am using the package plotrix radial.plot(). Yes, radial.plot() has a line type argument, lty, but that is for the polygons or the radial lines, not the radii or axes of the radial plot.....unless I am doing something wrong. Thanks!
First, even if you must post via Nabble, please do keep context. Now, as to your question: I think I now understand; you want control over the line type of the radial grid. You're correct; that's not currently possible with radial.plot(), but it's easy to modify the function and you can probably nudge Jim Lemon to make the change. In the meantime, here's a fix you can apply yourself: 1. Save the function code (either get the source or just use capture.output: capture.output(radial.plot, file = "rp.txt") 2. Edit the function; find the following two lines: polygon(xpos, ypos, border = grid.col, col = grid.bg) segments(0, 0, xpos, ypos, col = grid.col) and add the argument 'lty = grid.lty' to each. Then add 'grid.lty = 1' to the function arguments. Save the modified function as myradial.plot and source() it into your R session and then use it with whatever grid.lty setting you prefer.
