Overview

About

Maintained by Lysiane Charest6 releasesCRAN page ↗

birch is an implementation of the algorithms described in Zhang et al (1997), and provides functions for creating CF-trees, along with algorithms for dealing with some combinatorial problems, such as covMcd and ltsReg. It is very well suited for dealing with very large data sets, and does not require that the data can fit in physical memory.

Install

R (source archive)

url <- "https://cran.r-project.org/src/contrib/Archive/birch/birch_1.2-3.tar.gz"
pkgFile <- "birch_1.2-3.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 (1.2-3) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.
