Compute a kernel estimate over a grid and do a contour analysis
of this estimate. The contour heights the determined by finding
heights that exclude a certain fraction of the probability. For
example, the 95
and it should enclose about 5
are specified by the contour.levels
option; by default
they are c(5, 25, 50, 75, 95)
.

Raw density estimate drawn on area-preserving projection. Comprises same elements as above. |

Area of each individual contour. One level may have more than one contour; this shows the areas of all such contours. |

Data frame containing the total area within the contours at each level. |
