Dear mailing list members,

I am a new R user, I would like to plot the follewing data

var1 <- c(1,2,1,1,2,1,2,1,2,2)
var2 <- round(rgamma(10,2,1)/0.1)*0.1
var3 <- c(0,1,0,1,0,0,0,0,1,0)
var4 <- c(1,2,2,2,1,1,1,1,1,1)

Var <- data.frame(var1,var2,var3,var4)
Var <- Var[sort(Var$var1),]
tt <- Var$var1+((runif(length(Var$var1))/6)-(0.5/6))
labelname <- c("time 1", "time 2")

plot(tt,var2,xaxt = "n")
axis(1,1:length(unique(var1)), labelname)

Could you tell me please how can I get diffrent colour and plotting symbols according to var3 and var4, respectively.

Diego!
