[R] hide solid lines in symbols

[ben@zoo.ufl.edu]

  Two answers, both slightly klugey:

  1. use solid symbols instead of open symbols (e.g., pch=16 instead of
pch=1)

  2. use the solid-symbol equivalents to plot in the background color,
then use the open symbols

x <- runif(5)
plot(x,type="o",pch=16)
## or
plot(x,type="l")
points(x,pch=16,col=par("bg"))
points(x,pch=1)
