Overview

About

Maintained by Junrui DiCRAN page ↗GitHub ↗

Recent studies haven shown that, on top of total daily active/sedentary volumes, the time accumulation strategies provide more sensitive information. This package provides functions to extract commonly used fragmentation metrics to quantify such time accumulation strategies based on minute level actigraphy-measured activity counts data.

Install

R (source archive)pak (dev)

url <- "https://cran.r-project.org/src/contrib/Archive/ActFrag/ActFrag_0.1.2.tar.gz"
pkgFile <- "ActFrag_0.1.2.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 (0.1.2) 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("junruidi/ActFrag")

Development version from junruidi/ActFrag. Installs pak first if it is not already available.
