-package `dmmclust` is a package that provides functions for clustering small texts as described by [Yin and Wang (2014)](https://dbgroup.cs.tsinghua.edu.cn/wangjy/papers/KDD14-GSDMM.pdf) in *A Dirichlet Multinomial Mixture Model based Approach for Short Text Clustering*.

 The clustering algorithm is remarkably elegant and simple, leading to a very minimal implementation. This package also exposes some types to allow for extensibility.
