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.

If I understand it correctly, i takes my bivariate data and creates quantile density contours. My interpretation of these contours is that they enclose a certain % of the total data.

Are you looking for the contourLines() function ? Paul On 28/03/19 8:37 AM, Bernard McGarvey wrote:> John, I have attached a pdf of the plot.

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 looking for is the 2D curve that encloses say 95% of the data in a similar fashion to a 1D quantile where the quantile represents the value that x% of the data is below. I think what I am looking for is the 2D bivariate version of the 1D quantile plot (where the quantile value is plotted vs the % value). I hope this makes some sense.
