Configuring the C compiler path in RStudio

Question

I have different versions of gcc on my machine. I need to let RStudio use the specified version of gcc to compile the C files. But no matter how I modify the .bashrc file to change the default gcc system, RStudio always uses the same version. Anyway, can I customize the C compiler path in RStudio? Thank you

You can specify CXX and CC variables in ~.R/Makevars , for example

 CC="clang" CXX="clang++"
