## Not run: 
ggplot(mtcars, aes(x=factor(cyl), fill=factor(vs))) + geom_bar(position="dodge")
ggplot(diamonds, aes(x=price, fill=cut)) + geom_bar(position="dodge")
# see ?geom_boxplot and ?geom_bar for more examples

df <- data.frame(x=c("a","a","b","b"), y=1:4)
p <- qplot(x, y, data=df, position="dodge", geom="bar", stat="identity")

p + geom_linerange(aes(ymin= y - 1, ymax = y+1), position="dodge")

# Dodging things with different widths is tricky
p + geom_errorbar(aes(ymin= y - 1, ymax = y+1), width=0.2, position="dodge")
# You can specify the width to use for dodging (instead of the actual
# width of the object) as follows
p + geom_errorbar(aes(ymin= y - 1, ymax = y+1, width=0.2), position=position_dodge(width=0.90))
