Overview

About

Maintained by Chen ZhangCRAN page ↗GitHub ↗

Vector binary tree provides a new data structure, to make your data visiting and management more efficient. If the data has structured column names, it can read these names and factorize them through specific split pattern, then build the mappings within double list, vector binary tree, array and tensor mutually, through which the batched data processing is achievable easily. The methods of array and tensor are also applicable. Detailed methods are described in Chen Zhang et al. (2020) doi:10.35566/isdsa2019c8.

Install

R (source archive)pak (dev)

url <- "https://cran.r-project.org/src/contrib/Archive/VBTree/VBTree_0.1.1.tar.gz"
pkgFile <- "VBTree_0.1.1.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 (0.1.1) 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("CubicZebra/VBTree")

Development version from CubicZebra/VBTree. Installs pak first if it is not already available.
