Hello dear list members, Following previous correspondence, I wish to use an Rcpp function inside a package I'm authoring. However, I do not wish to force the user to install Rcpp, and if he does not wish to do so, I want to let him "fall back" on an R written function (which is 20-40 times slower, but it works). Looking at this Vignettes: http://cran.rstudio.com/web/packages/Rcpp/vignettes/Rcpp-package.pdf I see that including Rcpp in a package require the use of "depends" in DESCRIPTION. Is there a way to have Rcpp as "Suggests", and to later use "require" when loading the package, to decide if to load the Rcpp function or the R function? (alternatively, I could have a separate package only for that function, but that feels a bit like a "hack" to me)
Thoughts?
