This has the added benefit of being able to compare the heights of the different bars directly and avoids placing error bars in the middle of a bar.

It's also a good habit to specify the upper bounds of your plot since the error bars are going to extend past the height of your bars. I also provided some example of use of geom_errorbar() in this response. Summaryse R I hope one of these works for you or gets you to the solution you need. –Sam Dickson Sep 29 '15 at 14:54 add a comment| Your Answer draft saved Ggplot2 Stat_summary This can result in unexpected behavior and will not be allowed in a future version of ggplot2.

Why do units (from physics) behave like numbers? with_motif represents obervations with the specified motif and without_motif are observations without the motif. If you want y to represent values in the data, use stat="identity". library(ggplot2) library(Rmisc) library(plyr) mus2 <- summarySE(mus, measurevar="litium", groupvars=c("treatment", "group", "day"), na.rm = TRUE) mus2 mus3 <- mus2 mus3$group <- factor(mus3$group) ms.chl<- ggplot(mus3, aes(x=group, y=litium, fill=treatment)) + geom_bar(stat="identity", colour="black") + facet_grid(~day) +
Beyond this, it's just any additional aesthetic styling that you want to tweak and you're good to go! With stat="bin", it will attempt to set the y value to the count of cases in each group. This encourages us to continue.... it took me some time to reproduce your results with my own data as in my data the columns are NOT named "x" and "y", which (apparently) means that for the
