Bar chart with confidence intervals

Publication-ready bar chart with {ggplot2} I haven’t posted anything useful in a while so I decided to make a post that will hopefully be super useful for folks that need to create barcharts. I’ve had to make many presentations in front of clients that wanted to see bar charts with confidence intervals so the code that I’m sharing isn’t something that I randomly threw together this weekend; I actually used the code several times to generate publication-ready bar charts.
