`validate_outcomes_is_factor()` #90

Closed DavisVaughan closed 5 years ago

DavisVaughan commented 5 years ago

Currently can provide an easy implementation that can be replaced with #84

validate_outcomes_is_factor <- function(outcomes) {
  is_factor <- vapply(outcomes, is.factor, FUN.VALUE = logical(1))
  if (!all(is_factor)) {
    rlang::abort(paste0("The outcome must be a factor."))
  }
}
