I am using wireframe from the lattice package, with the shade option set to TRUE. When I output to PDF or Postscript, a line gets drawn around each polygon of my surface which causes ugly Moir? effects and doesn't make sense in my application (think the plot of Maunga Whau--gridlines don't make sense). This does not happen when I display on the screen-- then I just get the surface as intended. I have tried everything from playing with trellis.par.set() to changing the code of panel.3dwire, but nothing seems to remove these gridlines. Any idea would be greatly...

Dear all, I am using filled.contour and my x-axis consists of a vector of dates, formatted using as.POSIXct. When I assign this vector to x in filled.contour, the x-axis in the plot is correctly formatted as dates. However, when I use plot.axes=axis(1) in filled.contour the x-axis is not correctly formatted. I need to opt for the latter because I want to add additional lines and points to the

Dear all, I would like to generate a filled.contour plot with log x and y axis, however using: filled.contour(as.line,log="xy") results in a warning message. Does anybody knos what to do? Thanks Thomas
