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...
