What you posted here doesn't have regular quotation marks.  I'm not sure
about the opening one, but the closing one has been converted to a
guillemet.  R would never have accepted this as input, so what you're
showing is is probably not what you actually did.

You also don't say exactly what happened, just that it didn't work.

Could you please post again, simplifying to just one string that fails,
and explain exactly how it fails?  I am sure that having save() call
paste() will not result in any difference from just calling paste() on
its own, and likewise manually typing the full string should produce the
same result as constructing it via paste().  (But I am not sure that
paste() is producing what you want.)

> So if there is an accented vowel somewhere along the path already defined in R, and the name I want to give the file, the file name is so altered. If the is an accent only in one of the two, no problem. As I said, there was no such problem with R 3.1.2.
