A factor is a vector of integers, each of which is associated with a character 'label'. 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 …

‘factor(x, exclude = NULL)’ applied to a factor without ‘NA’s is a no-operation unless there are unused levels: in that case, a factor with the reduced level set is returned. ‘as.factor’ coerces its argument to …

There's nothing to handle the factor-to-integer (or numeric) conversion because it's expected that as.integer(factor) returns the underlying integer codes (as shown in the examples section of ?factor). …
