locations of grid lines
numeric matrix of values to plot
limits for the plot
levels for partitioning z
numbers of levels for partitioning z
color palette function
list of colors instead of color.palette
graphical parameters passed to plot.window() and axis()
A bare-bones version of filled.contour
that does not
plot a legend and accepts some additional graphical parameters like tick
marks.
