The error message arises because you are sometimes delimiting character
strings using non-ASCII open and close double quotes, '“' and '”', instead
of the old-fashioned ones, '"', which have no open or close variants.  This
is a language syntax error, so R didn't try to compute anything.

The others' comments are still valid - you need to read the files named by
these strings to produce R datasets and combine the datasets.
