I have a weird problem running R.app 3.3.2 under Mac OS X 10.10.5.
I was trying to interrupt a command line using various Control codes until I
discovered that “Esc” is the escape key. (Makes sense!)
Now I find that while I can enter new commands to R, they no longer echo back,
so I cannot see what I am typing. On unix terminals CTL-Q will reset this, but
it does not seem to work on the R console.
I tried
> system("stty echo")
but was told
stty: stdin isn’t a terminal
So I tried the following, but it did not give me any info I can use.
> isatty(stdin)
[1] FALSE
> stdin()
description class mode text opened can read
can write
"stdin" "terminal" "r" "text" "opened" "yes"
"no"
> stdout()
description class mode text opened can read
can write
"stdout" "terminal" "w" "text" "opened" "no"
"yes"
What have I done, and how can I reset it?
I know I can quit the R session and start again, but if I have lots of graphics
windows on the screen, I don’t want to lose them all and have to recreate them,
not to mention having to play with the par parameters again.
