[R] Can this be done in ggplot?

[Kenneth Roy Cabrera Torres]

A very dirty solution.

I hope someone can give a better solution:

library(ggplot2)
set.seed(1)
df <- expand.grid(g = factor(1:4), f = factor(c("a", "b", "c")))
df <- df[-1, ] # some factors are not present in certain groups
df$v <- runif(nrow(df))

library(dplyr)

df <- df %>% arrange(g, desc(v))
df$nv <- with(df, factor(paste(g,f)))
df$nv <- factor(df$nv, levels = df$nv)

ggplot(df, aes(x = nv , y = v, fill = f)) +
   geom_bar(position="dodge", stat = "identity")
