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.
