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.
If you are using write.table, then pay more attention to the append
parameter documented in the help file.

Subject: Re: [R] add data to a file while doing a loop
Without context, read reproducible code, it is hard to answer this
question. 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!

Hi,
I would like to know how can I keep adding data to a file while
doing a loop and without deleting the data of the previous
iteration. Thanks.
