kanjistat offers tools for processing and analyzing Japanese kanji characters. You can look up readings and meanings along with further dictionary information (to a large part provided by KANJIDIC2) including morphological details. You can plot kanji in your favorite font and process the resulting bitmap. You can represent kanji as nested lists of stroke paths (based on original data by kanjiVG), plot components in different color or display the tree structure, and analyze these decompositions and their individual strokes. Various old and new distance functions between kanji are implemented.

Install directly from GitHub by saying in R
remotes::install_github("dschuhmacher/kanjistat")If you want to use the function kanjidist, you will have
to install the GNU Linear
Programming Kit (and the R package ROI.plugin.glpk). To
work with precomputed kanjivec objects and the distance
matrix used for the kanjidist
website, download the R data package kanjistat.data
via
remotes::install_github("dschuhmacher/kanjistat.data")Kanji are represented in three different ways in this package:
as characters (or their Unicode codepoints) in the console.
as kanjimat objects, i.e., bitmaps
using a certain font-family and possibly other typographical
parameters.
as kanjivec objects, i.e., nested
lists of strokes given as paths. Recently these objects have become much
more important than the kanjimat objects.
See vignette("kanjistat") for the basics and
?kanjivec and ?kanjidist for more information
on the third point. Alternatively, visit the pkgdown page at https://dschuhmacher.github.io/kanjistat/.
