I have the code below which is taken from this question. It was working on my computer recently and now for no apparent reason I keep getting Error in dots_list(...) : attempt to apply non-function. If I remove the code editing the HTML style from lines 17 though 47 the code runs. Any ideas as to why it may not be running. A sessionInfo() call is also below. I should note re-installing R is not preferable because I have admin restrictions that would require me to get IT involved.
