I’m familiar enough with ggplot that I can make a quick plot pretty easily in most cases.1 But when it comes to fine-tuning the various plot aesthetics, like adjusting the legend position or rotating axis tick labels, I always have to look them up. Today, I will be writing about one of these pesky things: looking up the point shape options for geom_point. The available documentation for this isn’t great, so I thought it would be worthwhile to write my own reference.
