arguments lookup is disabled while R is busy

The code hints appear to be not working properly for me. In both the
editor window and in R GUI I see the subject line in parentheses
rather than the usual helpful text indicating what variables are
acceptable in a particular function.
Tab autocompletion is also non-functioning.

Any pointers?

Thanks,
Brandon

Yes, that is expected, since you need R to obtain those (it requires R code to run) and R is single-threaded, so you get all those hints only when R is not busy.

Cheers,
Simon

At the time I wasn't doing anything. The editor window was open and
the GUI window was waiting for input. It was working fine in Rstudio
so I switched briefly, and now after a few power cycles it's like it
was. Not sure what I did, but I guess it's ok.

Maybe I was not parsing your e-mail correctly - the title says "arguments lookup is disabled while R is busy" which is expected. So how to reproduce what you describe?

Thanks,
Simon

Simon,
Wires crossed methinks.

I took a photo (imgur link in first message). In it you can see the
bottom of the editor window which says, "(arguments lookup is disabled
while R is busy)". While in the GUI window, it is the prompt ">". When
I switched to the GUI window, it would say that in the bottom of the
GUI window. The hints and autocomplete weren't working.

My point is that it wasn't busy doing anything and yet it insisted it
was. I closed and reopened R a few times and nothing changed. Then I
went to Rstudio, in which the code hints and autocomplete was working.

After a few reboots, it no longer does this and I can not get it to
reproduce using similar code ( I no longer have the original code I
was working with because I changed it too much).

The only thing I can think of is that during this session, I updated
from R 3.2.1 to 3.2.2 and also updated a lot of packages. Perhaps a
reboot was in order?

Sorry for the noise.
Brandon
