https://stackoverflow.com/questions/46622243/ggplot-plot-2d-probability-density-function-on-top-of-points-on-ggplot Apologies for those who have seen it there also but I thought that this list of experts may have someone who knows the answer. I have the following example code: require(mvtnorm) require(ggplot2) set.seed(1234) xx <- data.frame(rmvt(100, df = c(13, 13))) ggplot(data = xx, aes(x = X1, y= X2)) + geom_point() + geom_density2d() It yields a scatterplot of X2 against X1 and a KDE contour plot of the density (as it should). My question is: is it possible to change the contour plot to display the contours of a two-dimensional density function (say dmvt), using ggplot2? The remaining figures in my document are in ggplot2 and therefore I am looking for a ggplot2 solution. Thanks in advance!
