see attached)? Thanks!
That wasn't clear in your original request. But it's easy.
To provide arguments for setting the circle/radius line types
separately is essentially the same process that I've already
shown you. Modify the same two lines that I referenced in the
previous discussion:
1. Change
polygon(xpos, ypos, border = grid.col, col = grid.bg)
to
polygon(xpos, ypos, border = grid.col, col = grid.bg,
lty = gridcircle.lty)
and
segments(0, 0, xpos, ypos, col = grid.col)
to
segments(0, 0, xpos, ypos, col = grid.col,
lty = gridradius.lty)
Then add two arguments to the function's argument list:
gridradius.lty = 1, gridcircle.lty = 1
Modification that will permit different colours for the
circles/radii is left as an exercise.

Hi Peter,
Thanks for the help. Being a beginner R user with little programming
experience, once I source in "myradial.plot" in my R session, what do
I use to plot. In other words, before I used radial.plot(), but now
when I state myradial.plot(), it tells me that it can find the
function.
Thanks,
Bern
You may be misunderstanding my suggestion.
I'll assume that you are editing the file saved by capture.output().
Let's call it 'rp.txt'. After making the edits that I suggested,
you will need to add
myradial.plot <-
at the front of the file. You save the resulting edited file, still
named 'rp.txt'. Now use source() on that file to get the modified
version of the radial.plot function into your R session.

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.
