Hi there, I picked it up from r.colors' grass manual:
http://colorbrewer2.org/ The code bellow cold be usefull for you explore simbols and colors. x11(900,500) par(mfrow=c(1,2)) x<-runif(20) y<-runif(20) plot(y~x, type="n") Number.of.symbols<-20 for (i in 1:Number.of.symbols) { points(y[i]~x[i], pch=i, cex=1.5) text((x[i]+0.02),y[i], i) } colors.list<-colors() Number.of.colors<-100 colors.list<-colors.list[1:Number.of.colors] plot(0:1,0:1, type="n") for (i in colors.list) { x<-runif(1) y<-runif(1) text(x,y, i, col=i) } cheers miltinho On Tue, Nov 24, 2009 at 6:01 PM, phoebe kong <sityeek...@gmail.com> wrote: > It should be 11 different groups, not 8. > > On Tue, Nov 24, 2009 at 3:00 PM, phoebe kong <sityeek...@gmail.com> wrote: > > > Hi, > > > > I want to draw a plot where the data set has 8 different groups.
