An updated version 0.1.4 of the RcppExamples package is now on on CRAN. RcppExamples contains a few illustrations of how to use Rcpp.
The NEWS entry is below: a new example was added illustrating use of the (vectorised) random-number generators for three of the different distributions — and showing how it perfectly reproduces the values one gets in R.
Thanks to CRANberries, you can also look at a diff to the previous release 0.1.3. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page
