Thanks Greg.
I guess another option is to call a C function directly. On Windows I
see there is a function _kbhit() in conio.h. Not sure if it would be
that simple.
Write a .c file
#include conio.h
int main(void)
{
int ch;
ch= _kbhit();
return ch;
}
Then do the necessary stuff to call
This works, but it is not quite what I need:
par(mar=rep(0,4))
while(1)
{
img1-matrix(runif(2500),50,50)
dev.hold(); image(img1,useRaster=TRUE); dev.flush()
img2-matrix(runif(2500),50,50)
dev.hold(); image(img2,useRaster=TRUE); dev.flush()
}
I would like to do this:
while(!kbhit())
You could create a tcltk window that looks for a button click and/or
key press and when that happens change the value of a variable. Then
in your loop you just look at the value of the same variable and break
when the value changes.
