Then you may be in trouble. R (and S before it) are not tidily
classifiable. R supports functional programming, and object-oriented
programming, but most large bodies of code would not satisfy a purist in
either area. S3 classes are a very weak OOP mechanism, and R code usually
has too much assignment to qualify as functional programming. It is also
quite possible to write old-fashioned purely imperative code in R [a Real
Programmer can write Fortran in any language], and some people do this.
So, in order to find out what is most widely used you need some way to
take a probability sample of R programs, and then some criteria for
classifying them. All you can get from this list is information on what R
supports, and a convenience sample of opinions on how programming should
be done, which won't be sufficient if this really is an important issue in
your thesis.
If you were willing to take published packages as representative
then CRAN and Bioconductor are available for sampling....
