[Rcpp-devel] Error when trying to your piSugar example
Hi Charles, I believe the problem is that the Rcpp package is installed in a directory with spaces in the path (C:/Program Files/R/R-2.15.1/library/) and that this is causing the problem. If you install into a library without spaces in the path everything should work correctly (see: http://stackoverflow.com/questions/9764495/how-to-get-rcpp-to-work-in-r-on-a-windows-xp-platform ) J.J.
