[R] easy graphics question

[Sundar Dorai-Raj]

Myriam,
Here's a simple script that lists the pch symbols:

plot(x=0,type="n",xlim=c(0,1),ylim=c(0,1))
for(i in 1:100) {
   j = i - 1
   x = j%%10/10
   y = j%/%10/10
   cat("(",x,",",y,",",i,")\n")
   points(x,y,pch=i)
}

No arrow that I see. Look up ?arrows instead.
