What would be the equivalent of geom_density2d in lattice? In essence I'm trying to create this graph with lattice:I don't think contourplot or levelplot is what i want and when trying it, it gives me a blank plot?
R: lattice equivalent of density2d in ggplot?
r;ggplot2
Use a custom panel function in which the density is estimated (e.g. using MASS::kde2d()):library(lattice)library(MASS)set.seed(1);dat <- data.frame(x=rnorm(100), y=rt(100, 5))xyplot(y~x, data=dat,       panel=function(x, y, ...) {         dens <- kde2d(x=dat$x, y=dat$y, n=50)         tmp <- data.frame(x=dens$x,                       y=rep(dens$y, each=length(dens$x)),                       z=as.vector(dens$z))         panel.levelplot(tmp$x, tmp$y, tmp$z, contour=TRUE,                         subscripts=1:nrow(tmp), region=FALSE, ...)         panel.xyplot(x, y, ...)       })
