i've interpreted what you may want to achieve, but mileage may vary

xquery version "1.0";

let $string := "test,test,test,test,test"
return
  for $text in tokenize($string,',')
  return
    <text>{concat('add some text: ', $text)}</text>

let $buzz := if ($n mod 5) then () else "buzz" 
return
  if ($fizz or $buzz) then concat($fizz,$buzz) else $n

I installed R via brew e.g.

>brew install R

which complained it needed fortran compiler which was solved with 

>brew install gfortran

then re ran brew R installation and no problems.

R is an object-oriented language with every object having a type (and being a member of a class)

*** What is R written in ?

R itself, c and fortran (autoconf, shell script)

though some R packages are in c++, Perl, etc
