In the R code above, we used the argument stat = “identity” to make barplots. Note that, the default value of the argument stat is “bin”.In this case, the height of the bar represents the count of cases in each category. Aug 11, 2019 · geom_col() doesn't perform any count or aggregation in your data, that is why you have to provide a y aesthetic with absolute values, your code is essentially stacking a little column (and text label) for each row in the dataset,if you want to perform summaries you have to operate manually in the dataset, see this example Jul 03, 2014 · The script below illustrates how to add one label per stack in a stacked bar chart using ggplot in R. In this case, labels indicate the sum of values represented in each bar stack. The idea is to create as many labels as bars, but assign text to only one label per stack, then plot labels according to stack height. Barplot of counts. In the R code above, we used the argument stat = “identity” to make barplots.
