R help - Oct 2016 - Is there a way to prevent Rscript from opening help page when given an error

I posted this on stackoverflow but there hasn't been any replies, does
anyone know a solution for this?





I am running a script via command line using Rscript nameOfmyRscript. I notice
that when there is an error, my browser would open with the help page. Now my
script contained repeated errors of the same type so my browser had 10 tabs of
the same help page. Is there a command or way to prevent R from opening up these
pages? I know that you can suppress all warnings by doing option(warn=-1) and
that you can use sink() to write errors and warnings to file. I currently have
the errors and warnings written to separate files, but the help page keeps
opening. I would prefer to not have any help pages open at all.

The following error would open the mean.html help page

Error in mean.default(workshop) :

(converted from warning) argument is not numeric or logical: returning NA


    Thanks

That's not standard behavior, although I can see that it might be desired in
a teaching situation. How was your installation of R created and on what
operating system. (Answering those two questions and other useful advice  are
offered in the Posting Guide which I would suggest you read in its entirety ...
now ... before you draft a response.)
