Hi Rstudio Community,
I'm running Rstudio 1.2.1327 on Windows 10. When editing C++ files, the C++ diagnostics are either absent or incorrect.
For example, when editing the following Rcpp file:
#include <Rcpp.h>
using namespace Rcpp;
// [[Rcpp::export]]
NumericVector timesTwo(NumericVector x) {
int n = x.size();
return x * 2;
}
The diagnostics suggest that int n = x.size(); will cause an error because
"member reference base type 'Rcpp::NumericVector' (aka 'int') is not a structure or union."
In other contexts, e.g. when editing Rcpp files in a package, no diagnostics appear at all.

Would greatly appreciate any guidance here,
I'm not able to reproduce. Can you provide any other information?
Can you try executing:
.rs.setClangDiagnostics(2)
and then attempting to save to trigger RStudio diagnostics once more? You should then see some libclang diagnostic output in the console that might give some more information.
Sure, here's the output of .rs.setClangDiagnostics(2)
.rs.setClangDiagnostics(2)

I wonder if the use of a 'short' path for the R include directory is causing issues? I'm surprised because the includes look correct otherwise.
What do you see in the 'working' case, e.g. when you're working within a project?
The diagnostics look similar for the "working" case, except this time the error for int n = x.size(); no longer appears.

Note the RcppArmadillo include now appears because I was already using Armadillo in my test R package (just to explain why it's new).
I'm still not able to reproduce, so any extra context you can provide to get a reproducible example would be helpful.
Here is the full Rstudio diagnostic report, maybe this will be helpful. Is there something else I could provide that would help?
