tuckerR.mmgg

This package performs Three-Mode Principal Components using Tuckers Models and plot interactive Biplot.Some experiment design generated three-way or three-mode data, repeated observations of a set of attributes for a set of individuals in different conditions. The information was displayed in a three-dimensional array, and the structure of the data was explored using Three-Mode Principal Component Analysis, the Tucker-2 Model.

Installation

You can install tuckerR.mmgg from github with:

# install.packages("devtools")
devtools::install_github("gusart/tuckerR_mmgg")

Important contribution of this package

The most important contribution of this package are the interactive biplot graphics and the application of the diffit() function to find the best combination of components to retain.

Example

This is a basic example which shows you how to solve a common problem:

library(tuckerR.mmgg)
#> 
#> Attaching package: 'tuckerR.mmgg'
#> The following object is masked from 'package:graphics':
#> 
#>     plot
data(maize_pop)
output <- tucker2R(maize_pop,amb=2,stand=TRUE,nc1=3,nc2=3)

Extract the core matrix.
