Also, do you know how to make the radial rings "black" and a little thicker??
A co-worker requested that the?be made a little darker and easier to see.
library(plotrix)
ions<-c(3.2, 5.0, 2.0)
ion.names<-c("Na","Ca","Mg")
radial.plot(ions, labels=ion.names, rp.type="s", start=90*(3.14159/180),
main="Dissolved ions in water", point.symbols=16,
point.col="green", grid.col="black",
radial.lim=c(0,6), show.centroid=FALSE, cex=4)
text(1,2, "Sodium is hot")
text(5,2, "Mg bitter")
