Definitely R, but IMO from the start learn it with tinyverse and Rcpp. I.e use it as a pipelining and glue language but don’t write any processing code in it. R is slow, and memory hungry. Having said that tinyverse basically calls methods written in C and has a beautiful syntax. As Rcpp let’s you write whatever needs to go quickly in c++ then easily expose it in R.
