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.
