Hello, I would like to draw the contour of a posterior distribution. However I only have simulated points from this posterior distribution. So I estimate the density of my posterior distribution : density(points) I get the mean, the max, the median I know I can plot this density estimate. However if I try : contour(z=density(points)) It does not work. How can I do that ? Besides how I can get the value of my density estimate at one point ? when I try density(points)(vector), R tells me it is not a function. Thank you very much. _________________________________________________________________ météo et bien plus encore ! [[alternative HTML version deleted]]
