Addition-ally, the na.strings argument can be used to spec-ify values that should also be converted to NA. In-versely, there is an argument na in write.table and its derivatives to define value that will

  • In a previous post, you covered part of the R language control flow, the cycles or loop structures. In a subsequent one, you learned more on how to avoid looping by using the apply() family of functions, which act on compound data in repetitive ways.
