See the section below on normed means for more information. This can be done in a number of ways, as described on this page. View(mtcars) We begin by aggregating our data by cylinders and gears and specify that we want to return the mean, standard deviation, and number of observations for each group: myData <- navigate here Value The function is called for its side effect, producing a plot.
