11.2 R Packages for text

Packages are like apps on your phone. They give you additional functionality. To use the tools in a package you first have to install it.

install.packages("sotu", dependencies = T)
install.packages("tm", dependencies = T)
install.packages("SnowballC", dependencies = T)
install.packages("wordcloud", dependencies = T)
install.packages("stringr", dependencies = T)

After you install it, just like on a phone, anytime you want to use the app, you need to open it. In R, we do that with library().

library(sotu)
library(tm)
library(SnowballC)
library(wordcloud)
library(stringr)
