I lose control on colors when I plot points with pch=1 or 16
(empty or solid circle) or any letter, say "A". For example:

 

x=runif(5)

y=runif(5)

pdf("plot.pdf")

plot(x, y,
type='p', pch=1, col = 1:5) #just black points

plot(x, y,
type='p', pch=0, col = 1:5) #points with different colors

dev.off()

 

This problem occurred for different versions of R under Mac
OS X 10.4. not sure whether this is true for other operating systems. I used my
most basic settings of R without any special package loaded. Any suggestions/ideas
would be appreciated.
