I have a 3 dimensional plot using filled.contour. Normally the function provides a grid or wire plot with lines referencing the y and x axis values. Is there a way to use only one direction, say the y or x only? I'm not sure this helps, but it would be similar to plotting data in a 2 dimensional plot and plotting the grid lines by nullifying one of the axes grids by using plot(1:3, 1:3) grid(nx=NA, ny=4) as opposed to plot(1:3, 1:3) grid() The only difference is that the grid in filled.contour has amplitude in filled.contour. Thanks in advance. _________________________________________________________________ eet. [[alternative HTML version deleted]]
