I will take a look but the hdrcde package appears to give me the plots I was
looking for.
Thanks

Excellent. I'll mention also the hdrcde package which addresses some of
your questions as well. It also

You might be wishing for a contour plot of the density, labeled by the
probability mass outside of each contour, but there is no general simple
connection between density contours and the mass inside of them. You can work
it out (I think) for elliptically contoured distributions, but I suspect t

To follow on Jeff, is there a function to do 2-D (double) numerical integration
in R?

Regardless of how many dimensions you have for independent variables, the
density is one-dimensional, and if you assume the density function has been
determined (e.g. by kernel estimation or by a Gaussian copula) then if you
integrate the density function along that dimension there will be uniqu
That thought had crossed my mind so thanks for that clarification Bert. i think
you are correct and so the plot I am looking at must be doing something
different than I was thinking.

You are missing a crucial point. The reals are well ordered; higher
dimensions are not. Therefore 2d quantile contours are not unique.
Of course assuming I understand your query correctly.

If I understand correctly the ContourLines function gives you the contour lines
when you put in the data. But before this I need to data to put into that
function. I think this is something like a 2D CDF of the data that then leads
to the 2D quantiles but I am not 100% sure. What I am basically
Are you looking for the contourLines() function ?

John, I have attached a pdf of the plot. Hopefully you can read this.
If I understand correctly, this plot is basically the 2-D version of the 1-D
quantile plot.
Thanks
