Overview

About

Maintained by Jurian Baas5 releasesCRAN page ↗GitHub ↗

Developed to assist in discovering interesting subgroups in high-dimensional data. The PRIM implementation is based on the 1998 paper "Bump hunting in high-dimensional data" by Jerome H. Friedman and Nicholas I. Fisher doi:10.1023/A:1008894516817. PRIM involves finding a set of "rules" which combined imply unusually large values of some other target variable. Specifically one tries to find a set of sub regions in which the target variable is substantially larger than overall mean. The objective of bump hunting in general is to find regions in the input (attribute/feature) space with relatively high values for the target variable. The regions are described by simple rules of the type if: condition-1 and ... and condition-n then: estimated target value. Given the data (or a subset of the data), the goal is to produce a box B within which the target mean is as large as possible.

Install

R (source archive)pak (dev)

url <- "https://cran.r-project.org/src/contrib/Archive/subgroup.discovery/subgroup.discovery_0.3.1.tar.gz"
pkgFile <- "subgroup.discovery_0.3.1.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (0.3.1) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("Jurian/subgroup.discovery")

Development version from Jurian/subgroup.discovery. Installs pak first if it is not already available.
