I tried using the command-line and indeed it does not buffer so that,
for example:
for (i in 1:5) {
print(x)
Sys.sleep(3) }
does as expected.
However, the following sleeps for 15 seconds and then produces no
output:
library("quantmod")
for (i in 1:5) {
getQuote("AAPL")
Sys.sleep(3) }
Why is that?
Thanks.

The binary in R.app starts the GUI. I suppose I would have to install
the command-line version separately.
On my machine there is a ``file'' /usr/bin/R which is actually a
symbolic
link to /Library/Frameworks/R.framework/Resources/bin/R.
The latter is an executable shell script.
At the command line in a window you should be able to just type
R
or (if /usr/bin is not in your path)
/usr/bin/R
or (if the symbolic link is not present in /usr/bin)
/Library/Frameworks/R.framework/Resources/bin/R
and get R going. In such a way as not to invoke the AQUA GUI.
If this doesn't work, I'm afraid I'm out of ideas.
If the last option works, then you should create the symbolic link
in /usr/bin
(and make sure that /usr/bin is in your path). Then you'll be able
to start
simply by typing ``R''.
cheers,
