Hello, I'm trying to track down more information on hdiffplot than what is supplied in ?hdiffplot. More specifically, the example code found at the bottom ?hdiffplot ("##Compare *three* of them:") is something I'm very interested in using for my own analysis. However, I don't see how to add a legend or even how to dig into the "bnlst" object that is created for determining what the displayed colors mean. The following example helps illustrate what I mean: library(hexbin) x1 <- rnorm(10000) y1 <- rnorm(10000) x2 <- rnorm(10000,mean=1) y2 <- rnorm(10000,mean=1) x3 <- rnorm(10000,mean=1) y3 <- rnorm(10000,mean=0) xbnds <- range(x1,x2,x3) ybnds <- range(y1,y2,y3) bin1 <- hexbin(x1,y1,xbnds=xbnds,ybnds=ybnds) bin2 <- hexbin(x2,y2,xbnds=xbnds,ybnds=ybnds) bin3 <- hexbin(x3,y3,xbnds=xbnds,ybnds=ybnds) erodebin1 <- erode.hexbin(smooth.hexbin(bin1)) erodebin2 <- erode.hexbin(smooth.hexbin(bin2)) erodebin3 <- erode.hexbin(smooth.hexbin(bin3)) bnlst <- list(b1=erodebin1, b2=erodebin2, b3=erodebin3) hdiffplot(bnlst) Can 'grid.hexlegend' be used to add a legend somehow? -Eric -- View this message in context: http://r.789695.n4.nabble.com/hdiffplot-tp3000644p3000644.html Sent from the R help mailing list archive at Nabble.com.
