Overview

About

Maintained by Junhewk KimCRAN page ↗GitHub ↗Issues ↗

R package based on 'Rcpp' for 'MeCab': Yet Another Part-of-Speech and Morphological Analyzer. It provides install-time engine profiles and dictionaries for Japanese, Korean, and Mandarin Chinese text. Runtime dictionary selection does not change the installed engine. This package utilizes parallel programming for providing highly efficient text preprocessing 'posParallel()' function. For installation, please refer to README.md file.

Changes in 0.0.1.7

Add dictionary_info() to report metadata for the dictionaries loaded by MeCab.
Add MECAB_LANG=zh as a first-class installation profile using standard MeCab 0.996 and the mecab-jieba 0.1.1 Mandarin dictionary.
Clarify that lang and set_dic() select dictionaries rather than MeCab engines, and document language-specific dictionary feature layouts.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)

install.packages("RcppMeCab", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("junhewk/RcppMeCab")

Development version from junhewk/RcppMeCab. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-rcppmecab

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-RcppMeCab

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager
