An R package for managing and analyzing text, created by Kenneth Benoit. Supported by the European Research Council grant ERC-2011-StG 283794-QUANTESS.

For more details, see https://quanteda.io.

quanteda 3.0 is a major release that improves functionality, completes the modularisation of the package begun in v2.0, further improves function consistency by removing previously deprecated functions, and enhances workflow stability and consistency by deprecating some shortcut steps built into some functions.

See https://github.com/quanteda/quanteda/blob/master/NEWS.md#quanteda-30 for a full list of the changes.

As of v3.0, we have continued our trend of splitting quanteda into modular packages. These are now the following:

• quanteda: contains all of the core natural language processing and textual data management functions
• quanteda.textmodels: contains all of the text models and supporting functions, namely the textmodel_*() functions. This was split from the main package with the v2 release
• quanteda.textstats: statistics for textual data, namely the textstat_*() functions, split with the v3 release
• quanteda.textplots: plots for textual data, namely the textplot_*() functions, split with the v3 release

We are working on additional package releases, available in the meantime from our GitHub pages:

• quanteda.sentiment: Functions and lexicons for sentiment analysis using dictionaries
• quanteda.tidy: Extensions for manipulating document variables in core quanteda objects using your favourite tidyverse functions

and more to come.

The normal way from CRAN, using your R GUI or

install.packages("quanteda") 

Or for the latest development version:

# devtools package required to install quanteda from Github 
devtools::install_github("quanteda/quanteda") 

Because this compiles some C++ and Fortran source code, you will need to have installed the appropriate compilers to build the development version.

See the quick start guide to learn how to use quanteda.
