Re: overlay plot

This is because you are using "RasterFill" for the second plot, which doesn't allow for transparency. When you use RasterFill, all the white areas in plot2 are actually white and not transparent, so they cover up everything in plot1.

Try using CellFill instead of RasterFill:

  res2@cnFillMode = "CellFill"
