I have a IMDB dataset and trying to make a boxplot of a film's ratings.
I've successfully loaded the dataset and tried to make the boxplot but it produced a really weird result.
It looked as it tried to make a boxplot for all the films and not just the one selected.
boxplot(rating ~ title, data=imdb[imdb$title == "Top Gun (1986)", ])
Factors retain their levels even after subsetting, you can drop those that are unused with
boxplot(rating ~ title, data=droplevels(imdb[imdb$title == "Top Gun (1986)", ]))
