I also tried converting variable place into class 'factor'.

Hi,

This code using facet_wrap works:

require(ggplot2)
DF <- data.frame(place=letters, value=runif(26), location=c(rep(1, 13),
rep(0, 13)))
qplot(data=DF, x=place, y=value, geom="bar", stat="identity") +
  coord_flip() +
  facet_wrap(~ location, scales = "free", ncol = 1)

And using facet_grid:

DF <- data.frame(place=letters, value=runif(26), location=c(rep(1, 13),
rep(0, 13)))
qplot(data=DF, x=place, y=value, geom="bar", stat="identity") +
  coord_flip() +
  facet_grid(. ~ location, scales = "free")

Note that I switched the formula in facet_grid. However, I would expect
your code to also work.

cheers and hope this helps,
Paul
