[R] symbols hidden in polar.plot

[Sumitrajit Dhar]

Hi Folks,

Here is my attempt at a simple polar plot.


 > pos <- seq(0,360,by=5)
 > tspk <- rep(c(1,0,1),c(13,47,13))
 > require(plotrix)
 > polar.plot(tspk,pos,rp.type="s",point.symbols=17,point.col="green4")


I only see half the symbols, the other half of each symbol is hidden  
under the circular grid. In fact if I change rp.type="r", I see the  
lines being plotted and then the grid gets plotted over it and hides  
the lines.

What am I doing wrong?

Regards,
Sumit
