R help - Jun 2010 - Order labels in qplot() - ggplot2 {help}

Hello,

I want to arrage the label according to my preference eg.. (va, vp, a, b,
c) but don't know how to supress default ordering. Any
suggestions?

Please try the code below:

n <- c("va", "vp", "a", "b",
"c")
p <- c(2, 2,1, 3,5)
pm<- c(3,4,2,5,4)
pn <- c(1,1,1,2,3)
x<-data.frame(cbind(n,p,pm,pn))
library(ggplot2)
qplot(x=n, y=p, data=x, ymin=pn, ymax=pm,
  xlab='', ylab='', main='Order Label as: va vp a b c')
+
  geom_hline(yintercept = 2) +
  geom_linerange() +
  coord_flip()

Thanks!

Hi,

You could reorder the factor levels before plotting,

x$n = factor(x$n, levels=c("va","vp", letters[1:3]))

last_plot() %+% x

or you could avoid using factors in the first place,

 x <- data.frame(cbind(n,p,pm,pn), stringsAsFactors=FALSE)

last_plot() %+% x

HTH,

baptiste
