[R] How to speed the shut down of the graphic device

[Philippe Hupé]

hello,

I use R1.7.1 under winXP and I am running the following script example :

for (i in 1:10)
{
       x <- rnorm(100)
       png( paste("D:/essai",i,".png",sep=""))
       plot(x)
       t1 <- Sys.time()
       dev.off()
       t2 <- Sys.time()
       print(t2-t1)
      
}

at each step, it takes about 3 seconds to shut down the graphic device. 
I want to generate about one hundred of image and of course it takes too 
much time. Is there any trick ?

Philippe
