Changing radii line type in radial plots

Hello all,

Is it possible to change the radii line type in radial plots? I wasn't able
to find anything online.

Do please be more specific: which package's radial plot function
are you using? Package plotrix has radial.plot() with an 'lty'
argument.

Peter Ehlers

Thanks,
Bern

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.

Hi bwone,
No, there is no way to change the line type of the grid in radial.plot 
at the moment. If you need to have different line types, you could 
change two lines in the function:

polygon(xpos,ypos,border=grid.col,col=grid.bg)
to
polygon(xpos,ypos,border=grid.col,col=grid.bg,lty=my.lty)

if(show.radial.grid) segments(0,0,xpos,ypos,col=grid.col)
to
if(show.radial.grid) segments(0,0,xpos,ypos,col=grid.col,lty=my.lty)

I might be persuaded to add yet another argument to the function if 
anyone else wants different line types.
