[S] Display of plots added to a graph

Dear S+ Users,

To create animation, I want the result of each plotting command within a
function to be displayed immediately upon completion of that command.
As is, everything is plotted upon exit (return) from the function.

How can I force the immediate display to a graphic window of the result of
a plotting command that is part of a function?

I am running v. 4.0 release 3 for Windows.


test.plot<- function(n)
# Plot three point, one at a time.
# Display each point once plotted.

x<- c(1,2,3)
y<- c(1,2,1)

plot(x,y, type="n")

nobs <- length(x)
for(i in 1:nobs) {
points(x[i], y[i])
pause(n) # pause for n sec

The pause function was kindly provided by Bert Gunter
pause<- function(n)
start <- proc.time()
while(proc.time() < (start + n)) {
#do nothing
cat("all done\n")

Thanks in advance!
