Thank you. I am using R 2.0.0 under Windows 2000.
I've tried 1. par(ask=T) 2. readline(prompt = "Pause. Press <Enter> to continue...") 1. script: x <- 0:20 y <- 5:25 plot(y) plot(x) plot(y~x) output: > par()$ask [1] TRUE > x <- 0:20 > y <- 5:25 > plot(y) Hit <Return> to see next plot: plot(x) ####R does not pause after plot(y) #### it seems R eats the second plot(x) > plot(y~x) Hit <Return> to see next plot: ####R does pause here 2. script: x <- 0:20 y <- 5:25 plot(y) readline(prompt = "Pause. Press <Enter> to continue...") plot(x) pause() plot(y~x) output: ####R does not pause at all > par()$ask [1] TRUE > plot(y) Hit <Return> to see next plot: readline(promp #seems plot() eats some characters > = "Pause. Press <Enter> to continue...") Error: syntax error > plot(x) Hit <Return> to see next plot: pause() > plot(y~x) Hit <Return> to see next plot: I don't know if I have made some stupid mistakes or messed up some of configurations. ************************************************************* On Sat, 27 Nov 2004 13:07:58 -0600, Marc Schwartz <[EMAIL PROTECTED]> wrote: > On Sat, 2004-11-27 at 11:42 -0500, Terry Mu wrote: > > > > I used pause() from library(DAAG) to pasue between plots.
