Call R Script from C code

Question

Is there a way to call R-Script inside C code?

I found R Api for C (chaper 6. of the guide "Writing R-Extensions"), but, as I understand it, this "only" allows us to name the C-implementation of R. Because of this, I could call R-Script through the shell, but there is no solution for me, since this does not allow the data to be transferred correctly (at least not if I do not want to write the data to a Csv file or something like that),

Is there an easy way to use the RC parser in advance?

Is there any reason you don't want to embed it? This is covered in this question: R of C - The Simplest Possible Helloworld ...

Answer 2

I found that this works to run Rscript in C ++ for Mac:

string r_command = "/usr/local/bin/RScript --vanilla /Users/<enter file path here>/your_script.R \"" + argument_1 + "\" " + "\"" + argument_2 + "\""; system(r_command.c_str()); 

You can also pass variables into arguments. Beware of shoots. Everything can become complicated.
