Re: [R] Superimposing Line over Histogram in Density Plot

I do it a bit differently: Once you've got myhist, you can plot a line on the existing histogram plot with something like: smoo<-spline(myhist$breaks[1:length(myhist$breaks)-1],myhist$counts) lines(smoo$x,smoo$y,col='green') You'll have to muck a bit with scale factors to make the spline curve

Re: [R] Superimposing Line over Histogram in Density Plot

try something like this: x <- rnorm(200) hist(x, col = "blue", freq = FALSE) lines(density(x), col = "red", lwd = 2) I hope it helps. Best, Dimitris Dimitris Rizopoulos Biostatistical Centre School of Public Health Catholic University of Leuven Address: Kapucijnenvoer 35, Leuven, Belgiu
