[R] ggplot2 geom_bar arrangement

[Brian Smith]

Hi,

I was trying to draw a geom_bar plot. However, by default, the bars are
arranged according to the label, which I don't want. I want the bars to
appear exactly as they appear in the data frame. For example in the code:

 Lab=c(letters[4:6],letters[1:3])
 valuex = c(3.1,2.3,0.4,-0.4,-1.2,-4.4)
 df <- data.frame(Lab,valuex)
 px <- ggplot(df,aes(Lab,valuex,label=Lab)) + geom_text(aes(y=0)) +
geom_bar(stat = "identity")
 px


The default arranges the bars in order 'a' through 'f', but I want them
arranged as per df.

How can I do this?

thanks!
