An R package consisting of dictionaries for text analysis and associated utilities. Designed to be used with quanteda but can be used more generally with any text analytic package (e.g. tidytext, tm, etc.).
# the devtools package needs to be installed for this to work
devtools::install_github("kbenoit/quanteda.dictionaries") With the liwcalike() function from the quanteda.dictionaries
package, you can easily analyze text corpora using exising or custom
dictionaries. Here we show how to apply the Lexicoder Sentiment
Dictionary (Young and Soroka 2012) to a corpus consting of 2000 movie
reviews (from the
quanteda.corpora
package).

dictionary = data_dictionary_NRC)
