As input this function uses the DTM, the word and the correlation limit (that varies between 0 to 1). To find associations between terms you can useВ the findAssocs()В function. If you want to have a visual representation of the most frequent terms you can do a wordcloud by using the wordcloud package. #put the data into a corpus for text processing

install.packages('tm') # if not already installed To implement some common text mining techniques I used the tmВ package (Feinerer and Horik, 2018). In this post I share some resources for those who want to learn the essential tasks to process text for analysis in R.
