Hi,
I have made a minimal example of my problem:
require(tcltk)
tt <- tktoplevel();
AUS <- function()
{
test("hello");
}
AUSButton.but <- tkbutton(tt,text="OK",command=AUS)
tkgrid(AUSButton.but)
tkfocus(tt);
test <- function(parameter) {
for (i in 1:100) {
for (j in 1:100000) { j <- j + 1;}
print(i);
flush.console();
}
}
There ist the function test (with a parameter), and this function does a
time-consuming calculation, but shows the progress with the numbers from 1 to
100.
When I click the button "OK", the tktoplevel window and R don't response
anymore and there are no numbers on the console until the outer for loop is
finished. Then there are printed out all numbers at once.
Is there a possibility to change the call of the function test() that R and the
tktoplevel window don't "crash" and the function test is "normally" executed at
the console?
Thank you!
