Ambika Choudhury

R is one of the popular languages for statistical computing among developers and statisticians. According to our latest report, R is the second most-preferred programming language among data scientists and practitioners after Python. The language ruled the preference scale, with a combined figure of 81.9 percent utilisation for statistical modelling among those surveyed.

Below is the list of top ten packages for NLP in R language one must know.

(The list is in alphabetical order).

1| koRpus

koRpus is an R package for analysing texts. It includes a diverse collection of functions for automatic language detection. It also includes indices of lexical diversity, such as type token ratio, MTLD, etc. koRpus’ also provides a plugin for R GUI as well as IDE RKWard that assists in providing graphical dialogs for its basic features.
