[Rcpp-devel] a question about missing rcpp.h

Dear all

I am using a Windows 7 system, R studio 0.99.467, R x64 3.3.1 and R tools 34.

I have been trying to run sourceCpp("reglinRcpp.cpp") in my R studio and got the following error message. It seems clear that the issue is that the Rcpp.h file cannot be found. So I have tried to run set PKG_CXXFLAGS='-I/H:/R/win-library/3.3/Rcpp/include' in the windows command window (see attached screenshot). However, this does not solve the issue. Could anyone advise me what I should do? Thanks a lot in advance!

Kind regards
