The method below is from Morey (2008), which is a correction to Cousineau (2005), which in turn is meant to be a simpler method of that in Loftus and Masson (1994). After this, we construct a ggplot object that contains information about the data frame we're using as well as the x and y variables.

In this case, the column names indicate two variables, shape (round/square) and color scheme (monochromatic/colored). # Convert it to long format library(reshape2) data_long install.packages("ggplot2movies") data(movies, package="ggplot2movies") Plot average Length vs Rating rating_by_len = tapply(movies$length, movies$rating, mean) plot(names(rating_by_len), rating_by_len, ylim=c(0, 200) ,xlab = "Rating", ylab = "Length", main="Average Rating by Movie Length", pch=21) Add error Instead of columns of means, we just need to supply barplot() with a matrix of means.
