getEndOfBizWeekwere not working right. These are convenience wrappers around the real functionality provided as a member function to the reference class built by Rcpp modules---which works off a reference instance of the class, and these two convenience functions were not updating the date. This is now fixed.
The complete NEWS entry is below:
Changes in version 0.2.1 (2012-08-08)
Bug for getEndOfBizWeek() and getEndOfMonth() who were lacking a call to fromDate(date) to actually pass the date for which the functions are computing the end of business week or month.
Courtesy of CRANberries, there is also a diffstat report for 0.2.1 relative to 0.2.0. As always, feedback is welcome and the rcpp-devel mailing list off the R-Forge page for Rcpp is the best place to start a discussion.
