Hi, in order to save space for a publication, it would be nice to have a combined scatter and density plot similar to what is shows on http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=78 I wonder if anybody perhaps has already developed code for this and is willing to share. This is the reproducible code for the histogram version obtained from the site: def.par <-

I've been trying to implement bivariate kernel density estimation. For data like mine, function "kde" from package "ks" with bandwidth matrix derived by function "Hscv" seems like a very good choice. Unfortunately, Hscv seems unmanageably slow except for very small sample sizes (up to a few hundred) and my sample sizes are quite large (up to a few thousand).

Hi, I'll try to keep my question brief and to the point, to anyone who helps 'THANK YOU!' I want to get a circle/ring/buffer or some other form of drawn line around certain points on a x,y plot, the points usually don't form a circle, often they form a 'wobbly' shape, so ideally I'd like something that follows the shape the points make. I'll start by explaining
