Hi there, I'm using the hexbin function to make some really snazzy density plots for extremely large datasets. I'm having some trouble getting the legend to look right. The lcex specified in the documentation for altering the legend text size does not seem to have any effect. No matter what lcex value I supply, the output looks the same. The normal cex values work fine. Is this a bug or am I missing something? The following program produces a beautiful plot with a very difficult to read legend. library("hexbin") data1 <- scan("data.txt",list(x=0,y=1)) x0 <- data1$x x1 <- data1$y hbin <- hexbin(x, y, xbins=100) plot.hexbin(hbin, xlab="stuff",ylab="other stuff", xlim=range(-1,1), ylim=range(-1,1), main="stuff vs other stuff", style = "nested.centroids", legend = 1, *lcex = 2.5*, cex.main = 2.5, cex.lab=2.5, cex.sub=2.5, cex.axis=2.5, minarea = 0.05, maxarea = 0.8, trans = NULL, inv = NULL, border = FALSE, density = -1, colramp = function(n){ LinGray(n,beg = 90,end = 15) }, verbose = getOption("verbose")) Cheers, Obi

The following however is reproducible and shows that you are right: xy <- MASS::mvrnorm(100000, mu = 1:2, Sigma = cbind(c(10,1),c(1,4))) library("hexbin") hbin <- hexbin(xy[,1], xy[,2], xbins=100) plot(hbin)# nice using gray scale plot(hbin, style = "nested.centroids")# legend not so nice ## try to improve legend; but it doesn't plot(hbin, main="x vs y", style = "nested.centroids", legend = 1, lcex = 2.5, ## <<<< cex.main = 2.5, cex.lab=2.5, cex.sub=2.5, cex.axis=2.5) --- You are correct. It's the hex.legend() function that 'lcex' (and more) is passed to, and unfortunately, that needs quite a bit of adaption before it could obey 'lcex' in the case of style = "nested.lattice" or "nested.centroids" --- because the hexagon symbols and the white space would also have to be enlarged. I've just committed slightly improved code to hexbin's development version; anyone interested in sitting down and improve the code, please drop us (Nicco & me) a line!
