Make R (statistics package) wait for keyboard prompt when run within a bash script

Question

I am using R to generate a series of plots within a loop, with the user hitting the enter key to indicate they have seen the plot and it is time to move on. These are interacti

Answer 1

Here is an example script that works for me (tested your first calling method on windows). It uses the tcltk package and creates an extra, small window with a single button, the script will pause (but still allow you to interact with the rgl window) until you either click on the 'continue' button on press a key while that window is active, then continue with the script.

library(tcltk)
library(rgl)

mywait <- function() {
    tt <- tktoplevel()
    tkpack( tkbutton(tt, text='Continue', command=function()tkdestroy(tt)),
        side='bottom')
    tkbind(tt,'', function()tkdestroy(tt) )

    tkwait.window(tt)
}


x <- rnorm(10)
y <- rnorm(10)
z <- rnorm(10)

plot3d(x,y,z)

mywait()

x <- rnorm(100)
y <- rnorm(100)
z <- rnorm(100)

plot3d(x,y,z)

mywait()

cor(x,y)
