I want to make a series of charts that have geom_bars with the same colour throughout. I prefer to be lazy and consequently, would like to avoid specifyingfill="blue" each time.
How does one amend a default value for a geom or create a new version with an amended default, in line with the latest version of ggplot2? Is it as simple as the below?
geom_bluebar <- function(...) geom_bar(fill="blue", ...)
