Dear Rolf, The problem persists with the function plot.im(), or plot (density ()), similar to with(bei.extra, plot (elev)). This problem occurs only with my personal machine, to another machine this problem does not occur. However, when I use another function, such kde2d () in the MASS package and perform the plot, the graph is obtained without problem.
