WebThe filter statement in dplyr requires a boolean argument, so when it is iterating through col1, checking for inequality with filter (col1 != NA), the 'col1 != NA' command is continually throwing NA values for each row of col1. This is not a boolean, so the filter command does not evaluate properly. answered Apr 12, 2024 by Zane Thanks Zane!

WebJan 31, 2024 · First, you create your own function that counts the number of NA’s in a vector.
