[R] Executing an R script and show the plots.

[Felix Blind]

Dear R users,

i am a python user trying to get my statistical knowledge up to speed
and R is the language for that.
I would like to run R scripts like that: R -f script.r and still get the
plots that pop up.

When I type the following code in the R REPL I get a nice plot:

library(ggplot2)                                                                                                                                                                          

data("midwest",
package="ggplot2")                                                                                                                                                        

ggplot(midwest, aes(x=area, y=poptotal)) + geom_point()

But when I put the same code in a file script.r and run it with R -f
script.r or if I source it in the REPL with source("script.r") I do not
get any plots shown.

Can you guys tell me what I do wrong. (Apart from either using RStudio
or the REPL exclusively)

Kind regards,
Felix
