Pairing Up Units and Vectors in Panel Data Setting (PairwiseD)
Pairing observations according to a chosen formula and facilitates bilateral analysis of the panel data. Paring is possible for observations, as well as for vectors of observations ordered with respect to time.

Yinyang’ K-Means and K-NN using NVIDIA CUDA (kmcudaR)
K-means implementation is based on ‘Yinyang K-Means: A Drop-In Replacement of the Classic K-Means with Consistent Speedup’. While it introduces some overhead and many conditional clauses which are bad for CUDA, it still shows 1.6-2x speedup against the Lloyd algorithm. K-nearest neighbors employ the same triangle inequality idea and require precalculated centroids and cluster assignments, similar to the flattened ball tree.

Maximal Complete Bipartite Graphs (biclique)
A tool for enumerating maximal complete bipartite graphs. The input should be a edge list file or a binary matrix file. The output are maximal complete bipartite graphs. Algorithms used can be found in this paper Y Zhang et al. BMC Bioinformatics 2014 15:110 <doi:10.1186/1471-2105-15-110>.

Measure Based Graphic Selection (mbgraphic)
Measure based exploratory data analysis. Some of the functions call interactive apps programmed with the package shiny to provide flexible selection options.

Tools for ‘CRAN’-Like Repositories (cranlike)
A set of functions to manage ‘CRAN’-like repositories efficiently.
