Bar Charts, Error Bars and R

A recent post on R Bloggers, linked to an article on DataScience+ that details how to use R to plot error bars on bar charts to indicate the variability in a particular variable. There are many other articles that detail this type of chart, sometimes referred to as “dynamite plots” which have a major flaw as the bar hides much of the information needed to make a decision on the variability of the data.
