Dear all! Thanks for reporting the issue. I observed the same problem, but I messaged not quickly enough... In fact, it seems that the ARM build of R (4.1.2) cannot pick up the data piped in when the —interactive flag is set. For reproducing I would suggest to use a simple “print(2.718)” instead of the string below.
So, here is what I got, just copied from the terminal (macOS 12.1) Pauls-Air:~ paul$ echo "print(2.718)" | R --quiet --no-save > print(2.718) [1] 2.718 > Pauls-Air:~ paul$ echo "print(2.718)" | R --quiet --no-save --interactive Pauls-Air:~ paul$ The first one gives the expected output, but when I force R to be in interactive mode, R somehow ignores the input from stdin. And we don’t know why :-) Thanks for your time and help! Best, Paul > On 23.
