Annotation Ticks on the axis
Hi all, I would like to have help in getting annotation ticks (corresponding to the minor grid) on my plot. Here is my toy example : par(mar=c(5, 6, 5, 5) + 0.1) x<-1:10 y<-x^2 plot(x,y,log="xy",xlab="log(x)",ylab="log(y)") par(new=T)

overlaying points and lines on a surface3d rgl plot with axes
Hi R users and experts, I am interested in learning more about the use of 3D plots. Specifically, I want to add points and lines to a surface plot. And get the axes and labels plotted also. Here is what I have tried with an example data set : library(rgl) vol2 <- 2*volcano # Exaggerate the relief library(reshape) mvol2 <- melt(vol2) str(mvol2) # First, persp and persp3d plots do not succeed
