I strongly suspect this is false. Most R functions have options to deal with NA, alas, not consistently though. See, e.g. ?na.omit . For manual processing, see ?NA (of course!). However, replacing NA's with 0's is dangerous. It may also be scientifically/statistically flawed; although properly dealing with missing data can be a very difficult issue.
