...+ scale_alpha(range = c(0,0.3), guide=FALSE) The above computes 2d density but it does not take the score (the weight into account). To do a weighted KDE I do : library(ks) mydensity <- kde(x = s_rit[,c(2,3)],w = s_rit$score) This computes a weighted KDE,but the data can't be passed to geom_raster because the x,y's are 151 each while the estimated density is a matrix 151 x 151. However this can be accepted by image as shown below. library(reshape2) library(ggplot2) x <- mydensity$eval.points[[1]] y <- mydensity$eval.points[[2]] z <- mydensity$estimate image(x,y,z) How can I...

...be labeled as str(yLabel) ?num [1:21] -88 -87 -86 -85 -84 -83 -82 -81 -80 -79 ... I have found on the internet that I can do something like that with ggplot2. For example you can run the following library(reshape2)library(ggplot2)m =matrix(rnorm(20),5)ggplot(melt(m),aes(Var1,Var2,fill=value))+geom_raster() What I see missing here is to get my matrix and transform it to a data frame with labels for x and y axis so as ggplot can print the values nice. If you get the idea this matrix will be printed as a two tile pattern let's say with black tiles zeros and white tiles black where a color bar wil...

Fwiw the engine behind geom_raster needs explicit observation-per-row form for input (with no structural normalization), so conversion to points is perfectly proper here, albeit confusing in context. (It's closer to what graphics devices actually use ultimately, but the expansion is laid out very early in ggplot2 because there&...
