Are you aware that this usually means R is waiting for the end of the
command, e.g. because a closing parenthesis is missing?

This command is not the same as the one you posted, it ends with two
parentheses... Could you post a whole copy/paste of the output,
including the beginning of the command? Have you tried copying the exact
contents of the command from your e-mail and check it still produces the
errors on your machine?

I think you should split the command in two parts, check if they work
separately. If one of them does not work, split it again, until you
identify either a problematic, possibly invisible char, or a length
limit...


My two cents
