ggplot(data = mpg, mapping = aes(x = displ, y = hwy)) + geom_point(mapping = aes(color = class)) + geom_smooth(data = filter(mpg, class == "subcompact"), se = FALSE)which causes the following error
Error in class == "subcompact" : comparison (1) is possible only for atomic and list typesI assume it worked when the authors wrote it, as they have a nice plot illustrating the results.
What is happening and how do I fix it? (R 3.3.2 on OS X)Thanks
The filter() function comes from the dplyr package. Be sure you"ve loaded it before running those lines. Otherwise, you"re running a comparison with class(), the built-in function, rather than mpg$class.
You are watching: Comparison (1) is possible only for atomic and list types
You probably had another package with a function (filter) loaded and masking dplyr filter
quick and dirty fix:
library(dplyr)ggplot(data = mpg, mapping = aes(x = displ, y = hwy)) + geom_point(mapping = aes(color = class)) + geom_smooth( data = filter(mpg, class == "subcompact"), se = FALSE)
