textblob

Integrates TextBlob with R.

Installation

First, install the package using remotes.

# install.packages("remotes")
remotes::install_github("news-r/textblob")

Then install the python dependencies, only do this one per virtual environment.

# replace with path of your choice
my_env <- "./env"

# run this (works on unix)
args <- paste("-m venv", my_env) 
system2("python3", args) # create environment
reticulate::use_virtualenv(my_env) # force reticulate to use env
# install textblob in environment
textblob::install_textblob(my_env)

Then download the necessary NLTK datasets, note that there is a lite version.

# download corpora
textblob::download_corpora() 

This will install textblob and download the necessary NLTK corpora.

Example

library(textblob)

string <- paste(
  "R is a programmming langage and free software",
  "environment for statistical computing and",
  "graphics supported by the R Foundation for",
  "Statistical Computing."
)

wiki <- text_blob(string) 

wiki$sentiment # get sentiment
#> Sentiment(polarity=0.4, subjectivity=0.8)

wiki$correct() # correct programmming langage
#> R is a programming language and free software environment for statistical computing and graphics supported by the R Foundation for Statistical Computing.

wiki$translate(to = "es") # translate
