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.

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!

Hello,
See
?open and ?capture.output
or
?textConnection
To open a connection (with 'open') then write to it is probably the
solution.

So you're looking for:
write.table(dataset, file=x.txt, append=TRUE)
Or do I understand your question wrongly?

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
Look at the documentation for whatever function you are using to write
data to the file.
It should be pretty obvious (look for an append argument).
Otherwise you'll have to provide more information, such as a short simple
example of what you have tried.

Using append=TRUE in many functions will work, but more slowly than opening a
connection once
