[R] Can this be done in ggplot?

Thanks Kenneth. That is the right idea for what I’m after. However,
creating a combined factor based on “g” and “f” is creating unwanted spaces
between the bars in the plot (I’d like to keep them adjacent within levels
of “g” as shown in my first plot).
I had the idea that ordering bars in ggplot with respect to a variable
within factor levels would be easier, but looks it is not.
Thanks again,
Axe.

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")

Hi,
I need to bars to display in order based on the values of "v" within each
group "g". Is this possible?
library(ggplot2)
set.seed(1)
df <- expand.grid(g = 1:4, f = factor(c("a", "b", "c")))
df <- df[-1, ] # some factors are not present in certain groups
df$v <- runif(nrow(df))
ggplot(df, aes(x = g, y = v, fill = f)) +
geom_bar(position="dodge", stat = "identity")
Thanks,
Axel.
