[R] buffering output to the console

[Berry Boessenkool]

Hey all,

I was wondering about the order of execution of functions and found that, in fact, I should look at the topic of buffering output to the console.
Which I did - below are some links of related topics, in case anyone wants to read up on it.

I decided to change the concerning lines in the file "Rconsole" in the "etc"-folder to
   ## Default setting for console buffering: 'yes' or 'no'
   buffered = no
which works fine.
Of course, when I send functions to someone else using a GUI console, I'll insert flush.console() at the important positions.

My question is:
should I expect serious computing time issues with this setting?
As posted in [5], calling flush.console too often takes a lot of time...


Thanks very much,
