The thing is, R interoperates very well with C, C++ and Fortran.  So when someone who uses R needs to solve one of those problems, they&#x27;ll generally just use C, C++ and Fortran, then you can call the function&#x2F;program from R, get your results, chart&#x2F;analyse them, etc...<p>And of course, R makes data exploration, statistics, and all those easier problems incredibly simple.
