Hi Rui,
Unfortunately, the code Rcpp::Rcout << "---------->>>>>.My values" <<
"\n"; still not printing the value.
Regarding your second suggestion, R_Print("My values\n"); - where
should I put this statement?

Hi,
I am using an R package where there are some C++ code.
To check some intermediate values generated by that C++ code, I added
a line like
std::cout << "My values";
Now with this modification, I next build a modified package (source) using
R CMD build
Next I install this modified package using install.packages() function
However during the run-time of the C++ code with above modification, I
dont get any print with "My values"
Can you please help to understand why am not getting that printed?

Hello,
If the package uses Rcpp try instead
Rcpp::Rcout << "My values" << "\n"; // or std::endl
More generally, there is also
R_Print("My values\n");
Hope this helps,
Rui Barradas
Hello,
Put R_Print where your cout is and instead of it.
As for Rcpp::Rcout, instead of "\n" try ending the line with std::endl
to immediately flush the buffer.
Hope this helps,
Rui Barradas
