I try both RStudio 1.2 stable and preview version, both can't show diagnostic and code completion for Rcpp, although I have click the option "Show diagnostic for c/c++" and select the option "automatically" for "Show code completion". then I return back to "RStudio-1.1.453.exe", it works again. Is this a bug is RStudio 1.2 ?
