Well we see that the header file declaring RcppVector is not loaded so

  -- either you made a mistake in your Makefile or src/Makevars

  -- or you upgraded to Rcpp 0.9.0 or later and didn't switch to 
     RcppClassic as RcppVector is an old class from the old API

But as you didn't tell us what you did and how you did it, we can't help any
more.  See eg the r-help guidelines for good error reports, similar sets of
minimal information (ideally a small set of steps to replicable the issue)
apply here too.

Dirk
