SOM Bound to Realize Euclidean and Relational Outputs (SOMbrero)
The stochastic (also called on-line) version of the Self-Organising Map (SOM) algorithm is provided. Different versions of the algorithm are implemented, for numeric and relational data and for contingency tables. The package also contains many plotting features (to help the user interpret the results) and a graphical user interface based on shiny (which is also available on-line at http://shiny.nathalievilla.org/sombrero).
Easy Data Manipulation, Data Quality and Statistical Checks (StatMeasures)
Offers useful functions to perform day-to-day data manipulation operations, data quality checks and post modelling statistical checks. One can effortlessly change class of a number of variables to factor, remove duplicate observations from the data, create deciles of a variable, perform data quality checks for continuous (integer or numeric), categorical (factor) and date variables, and compute goodness of fit measures such as AUC for statistical models. The functions are consistent for objects of class ‘data.frame’ and ‘data.table’, which is an enhanced ‘data.frame’ implemented in the package ‘data.table’.
Functions for Generalized Dissimilarity Modeling (gdm)
A toolkit with functions to fit, plot, and summarize Generalized Dissimilarity Models.
