Barplot With Error Bars Ggplot2
We'll use the myData data frame created at the start of the tutorial. Adding error bars to barplots in R is a lot of hand work which is very frustrating and complicated. Remember above that I created the barplot in the variable bp?
- Thankfully, there is!
- We use srt = 45 for a # 45 degree string rotation text(x = barCenters, y = par("usr") - 1, srt = 45, adj = 1, labels = myData$names, xpd =

- The natural way for statisticians is to use a boxplot, and ggplot2 makes that easy: qplot(class, hwy, fill=factor(year), data=mpg, geom="boxplot", position="dodge")+theme_bw() But Jarrett Byrnes, a marine community biologist, wanted to use
- The complete R script and data used to create these 2 graphs are available here!
- The standard error is defined as the ratio of standard deviation to the square root of the sample size.

For horizonal charts, ylim is really the x-axis range, excluding differences. If you leave it out, R will generate a separate plot just with the whiskers. other parameters passed to all graphics functions.

They are representing the boundaries for the confidence interval in which the true mean values lays somewhere (with 95% chance). Adding Standard Error Bars In R This interval is computed by subtracting/adding the adjusted standard error of the mean for the lower/upper value. We can get them as a vector by getting the first column of bp by >print(bp[,1])  0.7 1.9 3.1 So far so good.

The values for the y vector are trivial, since these are just our mean values, we computed above.
