Building on Duncan's code, here's an approximation to the Matlab 'peaks' plot referred to by Pedro: peaks <- function(x, y) { 3 * (1-x)^2 * exp(-(x^2)-(y+1)^2) - 10 * (x/5-x^3-y^5) * exp(-x^2-y^2) - 1/3*exp(-(x+1)^2-y^2)} x <- y <- seq(-3,3,.1) z <- outer(x,y, peaks) z2 <- 10 * round(c(z) + ab

Re: [R] persp plot + plotting grid lines

This wiki page has the answer. Draw the plot first to establish the coordinate system and create the viewing transformation matrix. Draw the grid lines with lines(trans3d()), and then put a: par(new=T) ... and then redraw the plot over the gridlines.

Re: [R] persp plot + plotting grid lines

Ideas... not a solution. Plot the grid within your ranges using something along the lines, literally and figuratively, based on the second example of persp's help pages. For the z=8 grid lines on that example you could use: for (ix in seq(-10,10, by=5)) lines (trans3d(x=ix, y=seq(-10,10,

Dear all; Does anyone know how to add grid lines to a persp plot? I've tried using lines(trans3d..) but the lines of course are superimposed into the actual 3d surface and what I need is something like the plot shown in the following link: http://thermal.gg.utah.edu/tutorials/matlab/matlab_tutorial
