What are factor levels in R?
In R, factors are a class of data that allow for ordered categories with a fixed set of acceptable values.
Typically, you would convert a column from character or numeric class to a factor if you want to set an intrinsic order to the values (“levels”) so they can be displayed non-alphabetically in plots and tables..
