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.

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.)
