Hi all, I've got a data frame with NA values scattered throughout. I would like to find the rows which contain an NA. Trying to find the indices of the NAs with grep() doesn't work (apparently you can't convert NA to "NA" character value, even with as.character()) so I was hoping someone could tell me how to find rows which contain NA. Thanks in advance, -Ken
