koRpus is an R package for text analysis. This includes, amongst others, a wrapper for the POS tagger TreeTagger, functions for automatic language detection, hyphenation, several indices of lexical diversity (e.g., type token ratio, HD-D/vocd-D, MTLD) and readability (e.g., Flesch, SMOG, LIX, Dale-Chall, Tuldava).
koRpus also includes a plugin for RKWard, a powerful GUI and IDE for R, providing graphical dialogs for its basic features. To make full use of this feature, please install RKWard (plugins are detected automatically).
More information on koRpus is available on the project homepage.
There are three easy ways of getting koRpus:
The latest release that is considered stable for productive work can be found on the CRAN mirrors, which means you can install it from a running R session like this:
install.packages("koRpus")
The CRAN packages are usually a bit behind the recent state of the package, and only updated after a significant amount of changes or important bug fixes.
Inbetween stable CRAN releases there's usually several testing or development versions released on the project's own repository. These releases should also work without problems, but they are also intended to test new features or supposed bug fixes, and get feedback before the next release goes to CRAN.
Installation is fairly easy, too:
install.packages("koRpus", repo="https://reaktanz.de/R")
To automatically get updates, consider adding the repository to your R configuration. You might also want to subscribe to the package's RSS feed to get notified of new releases.
If you're running a Debian based operating system, you might be interested in the precompiled *.deb packages.
To install it directly from GitHub, you can use install_github() from the devtools package:
library(devtools)
install_github("unDocUMeantIt/koRpus") # stable release
install_github("unDocUMeantIt/koRpus", ref="develop") # development release
Have a look at the l10n repository for packages called koRpus.lang.*.
By installing and loading these packages, you can add support for more languages to koRpus.
To ask for help, report bugs, suggest feature improvements, or discuss the global development of the package, please either subscribe to the koRpus-dev mailing list, or use the issue tracker on GitHub.
Please note that all development happens in the develop branch. Pull requests against the master
branch will be rejected, as it is reserved for the current stable release.
