I am dealing with a tibble with column name N(m). I want to use filter with !is.na() to remove empty rows.
if I went with filter(!is.na(N(m))), it gave an error 'could not find function "N"'
if I went with filter (!is.na('N(m)')), no error was reported but the empty rows were not removed.
I am wondering what should be the correct way to handle this.
