about 19 hours ago. Feel free to browse the archives either:
- on r-forge : http://lists.r-forge.r-project.org/pipermail/rcpp-devel/
- on gmane : http://news.gmane.org/gmane.comp.lang.r.rcpp
this thread has the information:
> After installing the latest version of Rcpp, my code that called Rmath

You can just prefix your calls with Rf_, so instead of calling dnorm,
you call Rf_dnorm, etc ...
You can use the RCPP_VERSION macro if you want this to work accross Rcpp
versions, something like :
#if defined(RCPP_VERSION) && RCPP_VERSION >= Rcpp_Version(0,8,6)
# define my_dnorm Rf_dnorm
# define my_dnorm dnorm
> Any suggestions?
