Extensible Data Structures for Multivariate Analysis.
multivarious
This package is intended to provide some basic abstractions and default implementations of basic computational infrastructure for multivariate component-based modeling such as principal components analysis.
The main idea is to model multivariate decompositions as involving projections from an input data space to a lower dimensional component space. This idea is encapsulated by the projector
class and the project
function. Support for two-way mapping (row projection and column projection) is provided by the derived class bi-projector
. Generic functions for common operations are included:
project
for mapping from input space into (usually) reduced-dimensional output spacepartial_project
for mapping a subset of input space into output spaceproject_vars
for mapping new variables (“supplementary variables”) to output spacereconstruct
for reconstructing input data from its low-dimensional representationresiduals
for extracting residuals of a fit withn
components.
Installation
You can install the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("bbuchsbaum/multivarious")
Example
This is a basic example which shows you how to solve a common problem:
library(multivarious)
#>
#> Attaching package: 'multivarious'
#> The following object is masked from 'package:stats':
#>
#> residuals
#> The following object is masked from 'package:base':
#>
#> truncate
