Felix,
I suggest you consider using an IDE such as RStudio as you develop and run R
code. An integrated development environment will allow you to concentrate on
learning R
rather on the mechanics of running R in a
non-standard environment.

You need to understand that the R interpreter does not have an interactive
plot device when run as a script from an OS command line. You need to open an
output device, `print` the output of the ggplot call, and then _after_ closing
the device appropriately, open the output in an appropriate viewer supplied by
your unstated OS.
?Devices # brings up a list of possible devices and has a "See Also" section
that says:
===========================
The individual help files for further information on any of the devices listed
here;
on Windows:
windows.options,
on a Unix-alike:
X11.options, quartz.options,
ps.options and pdf.options for how to customize devices.
dev.interactive, dev.cur, dev.print, graphics.off, image, dev2bitmap.
On Unix-alikes only:
capabilities to see if X11, jpeg, png, tiff, quartz and the cairo-based devices
are available.
==============================
So do some further reading to educate yourself.

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
