Hi all,
I'm an R newbie,
I did this script to create a scatterplot using the "tree" matrix from
"datasets" package:

library('datasets')
with(trees,
{
plot(Height, Volume, pch=3, xlab="Height", ylab="Volume")
symbols(Height, Volume, circles=Girth/12, fg="grey", inches=FALSE,
add=FALSE)
}
)

I'd like to use the column Named "Height" to fill the circles with colors
(ex.: the small numbers in green then yellow and the high numbers in red).
I'd like to have a legend for the size and the colors too.
I did it manually using a script like that:
color[(x>=0.001)&(x<0.002)]<-"#41FF41"
color[(x>=0.002)&(x<0.003)]<-"#2BFF2B"
color[(x>=0.003)&(x<0.004)]<-"#09FF09"
color[(x>=0.004)&(x<0.005)]<-"#00FE00"
color[(x>=0.005)&(x<0.006)]<-"#00F700"
color[(x>=0.006)&(x<0.007)]<-"#00E400"
color[(x>=0.007)&(x<0.008)]<-"#00D600"
color[(x>=0.008)&(x<0.009)]<-"#00C300" and so on but I don't like to do it
manually... do know a solution...
Thank you very much
chris
