Thanks for the reply. Every iteration produces a text data.frame directly into a file without saving it in R. And every iteration overwrites the data produced from the previous iteration. So what I would like to do is being able not to overwrite the data of any iteration but adding it to the same file with maybe the functions paste or rbind.

What system are you on? Do you need to write one line of data or a data frame or a list out? Are trying to write a graphic out? It will be easier to answer your question with some context. Good luck!
