Mixtures of Multivariate Shifted Asymmetric Laplace (SAL) Distributions (MixSAL)
The current version of the ‘MixSAL’ package allows users to generate data from a multivariate SAL distribution or a mixture of multivariate SAL distributions, evaluate the probability density function of a multivariate SAL distribution or a mixture of multivariate SAL distributions, and fit a mixture of multivariate SAL distributions using the Expectation-Maximization (EM) algorithm (see Franczak et. al, 2014, <doi:10.1109/TPAMI.2013.216>, for details).

Connecting to Various Database Platforms (DatabaseConnector)
An R ‘DataBase Interface’ (‘DBI’) compatible interface to various database platforms (‘PostgreSQL’, ‘Oracle’, ‘Microsoft SQL Server’, ‘Amazon Redshift’, ‘Microsoft Parallel Database Warehouse’, ‘IBM Netezza’, ‘Apache Impala’, and ‘Google BigQuery’). Also includes support for fetching data as ‘ffdf’ objects. Uses ‘Java Database Connectivity’ (‘JDBC’) to connect to databases.

Machine Learning of Hyperrectangular Gating Strategies for High-Dimensional Cytometry (hypergate)
Given a high-dimensional dataset that typically represents a cytometry dataset, and a subset of the datapoints, this algorithm outputs an hyperrectangle so that datapoints within the hyperrectangle best correspond to the specified subset. In essence, this allows the conversion of clustering algorithms’ outputs to gating strategies outputs. For more details see Etienne Becht, Yannick Simoni, Elaine Coustan-Smith, Maximilien Evrard, Yang Cheng, Lai Guan Ng, Dario Campana and Evan Newell (2018) <doi:10.1101/278796>.
