[Rprotobuf-commits] r597 - pkg/inst/unitTests

[noreply at r-forge.r-project.org]

Author: murray
Date: 2013-12-27 02:30:03 +0100 (Fri, 27 Dec 2013)
New Revision: 597

Added:
   pkg/inst/unitTests/runit.int32.R
Log:
Add a unit test of setting int32 fields with character vectors and
make sure we correctly raise exceptions in the appropriate cases
rather than crashing R since Rcpp::as<int> can't handle string types.



Added: pkg/inst/unitTests/runit.int32.R
