a data frame with label and freq columns. Details.

Compared to table + as.data.frame, count also preserves the type of the identifier variables, instead of converting them to NA: ‘Not Available’ / Missing Values Description. NA is a logical constant of length 1 which contains a missing value indicator.NA can be coerced to any other vector type except raw.
