FAQ: Axes • ggplot2

r - How do you specifically order ggplot2 x axis instead of ... When you create a factor by reading a column of character values in a text file (e.g. .csv), R assigns the integer values in alphabetical order rather than in the order they appear in the file. You can argue whether that makes sense, but ggplot2 then does the logical thing, which is to display the factor levels in order of their integer values.
