Oh, if plot does the thing, then you just want to specify the color argument accordingly, where the color argument is given by your production figure.
x=seq(1:100) y=seq(1:100) x.coord=sample(x,100) y.coord=sample(y,100) production=sample(1:100, 100) plot(y.coord~x.coord) #now lets say we want full instead of empty points plot(y.coord~x.coord, pch=16) #now lets say we want the points blue plot(y.coord~x.coord, pch=16, col="blue") #now lets say we want them in the same blue but with saturation varying by the production number plot(y.coord~x.coord, pch=16, col=rgb(0,0,100,production,maxColorValue=100)) #note that you may want to have maxColorValue=max(production) (or scale the production value accordingly) #and that you may want to have the color value (here for blue) also at that same value #now lets do red instead plot(y.coord~x.coord, pch=16, col=rgb(100,0,0,production,maxColorValue=100)) HTH, Daniel -- View this message in context: http://r.789695.n4.nabble.com/How-to-draw-a-graphic-using-data-with-coordinates-and-production-rate-tp2197568p2217136.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
