Perfect, thanks for the feedback.  

Most uses of the old API should be fixed by the one or two simple steps
outlined in the RcppClassic vignette.

|     | Hi Dirk,

|     | I have used Rcpp to integrate C++ into R and successfully built my

|     2.12.1,
|     | the same code could not be compiled. The error is like
|     |
|     | error: ‘RcppVector’ was not declared in this scope.
|     |
|     | Do you have any idea what is going on? Thanks.
| 
|     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.
