Let's assume you have a vector of "average values" avg and another vector of "standard deviations" sdev, they are of the same length n. Points, shown in the plot are the averages, and their ranges correspond to minimal and maximal values. ggplot(melt(df, id.vars=c("method", "N")), aes(method, value)) + geom_bar(stat="identity") + facet_wrap(~variable) share|improve this answer answered Nov 5 '13 at 20:28 Señor O 11.1k1730 add a comment| Not the answer you're looking for?
