Hi Pavel,
I probably should have explained that an object name beginning with a
number is not valid. See "An Introduction to R", section 1.8. I think
that the invalid name "2013fixed.data" has somehow been generated. If
you can find where this occurred and change it to "fixed2013.data" the
original error should disappear.
