verify_data_frame() function #42

Closed wibeasley closed 6 years ago

wibeasley commented 6 years ago

Does this function have enough use to include in the package?

verify_data_frame <- function( d, minimum_row_count=100L ) {
  # Verify that a legit data.frame was returned (and not an error message)
  checkmate::assert_class(d, "data.frame")

  # Verify at least 100 rows were returned (or whatever the argument value was).
  checkmate::assert_integer(nrow(d), lower=minimum_row_count, len=1, any.missing=F)
}
