Hi Thierry,
Thanks for the reply. I tried this:
> dat <- read.table("http://dpaste.com/88561/plain/";)
But I got such error:
> ggplot(dat, aes(x = V1, colour = factor(V2))) + geom_density()
Error in density.default(data$x, adjust = adjust, kernel = kernel,
weight = data$weight, :
need at least 2 points to select a bandwidth automatically
> ggplot(dat, aes(x = V1, fill = factor(V2))) + geom_density(alpha = 0.2)
Error in density.default(data$x, adjust = adjust, kernel = kernel,
weight = data$weight, :
need at least 2 points to select a bandwidth automatically
> ggplot(dat, aes(x = V1)) + geom_density() + facet_wrap(~V2)
Error: could not find function "facet_wrap"

Maybe I miss something? What could possibly go wrong?
