Hello everyone, I am trying to prune a data frame for partial least squares analysis. I need to delete an entire row if one cell in the row contains a NA. Presently, I am running a loop that is supposed to extract the rows that are full of numbers into a second data frame and skips the rows that contain a single NA value. I want to know if there is a simple way to determine if a row (about 20 columns) contains a single NA value without running a loop that checks each individual cell. Thanks in advance. __________________ Payam Minoofar, Ph.D. Scientist Meissner Filtration Products 4181 Calle Tesoro Camarillo, CA 93012 +1 805 388 9911 ext. 159 +1 805 388 5948 fax payam.minoo...@meissner.com
