The documentation says NA values are silently dropped. In a character variable with only NA this may lead to some unexpected downstream behaviour:
NA
# silently dropped modelr::typical(c("A", rep(NA_character_, 3))) #> [1] "A" # most frequent modelr::typical(NA) #> [1] NA # length zero NULL value causes errors downstream modelr::typical(rep(NA_character_, 3)) #> NULL #> Warning message: #> In max(counts) : no non-missing arguments to max; returning -Inf
If this is the intended behaviour I will modify my code accordingly.
