I am trying to control a background R session, connected via a fifo /
named pipe.
Is the fifo significant here? If I read the same R code from a file
via `<` I get the input echoed (R 3.4.4, Ubuntu).
Yeah, for a file I get echo on both macOS and Linux, but not on Windows.
I think the most useful behavior for --slave is no echo at all, maybe?
But I might be missing the motivation behind --slave.
Another thing is that windows does not have --interactive. Is there a
way to run R
1) without echoing stdin, and
I'm not seeing an echo for your example on Ubuntu or Fedora.
Interesting. Do you mean the fifo example, or just a file? Or both?
I wonder what this depends on then....
The fifo one -- I didn't try a file.
Particularly interesting that this does echo on macOS:
echo '1+1' | R --slave --interactive
But the FIFO example does not.
Anyway, it seems that if I remove --interactive then I get no echo.
Looks like this has to do with readline, which --interactive turns on.
If I use '--no-readline --interactive' (in that order) on Mac OS and
Linux I get no echo.
The code in R for all this should be identical on Linux and Mac OS --
both use the unix code. readline libraries may differ, shell/stty
settings may differ for your setup.
Best,

2) without quitting on the first error,
on all platforms?
One option is to use
options(error = function() invokeRestart("abort"))
This seems good enough for my use case, thanks much!
Luckily, this also solves the "disabling the crash dialog" problem, which I
have if I specify --interactive.

There may be better ways.
Best,
