Implementation of cross-calibration and precision analysis for HR-pQCT.

Description

XcalRep (x-calibration & reproducibility) is an R implementation of methods used for cross-calibration and precision analysis of HR-pQCT It enables cross-calibration and precision analysis in R for single- and multi-centre studies, conducted at single or multiple timepoints. XcalRep was developed with intended use for HR-pQCT, however, it easily extends to other instruments which undergo routine calibration and reproducibility assessment.

The XcalRep package provides the following utilities:

  • single and multi-site precision error calculation (CV and SD-based errors)
  • reference site selection
  • scanner cross-calibration

Additionally, the XcalRep package provides multiple visualization tools to evaluate scanner reproducibility.

Visit XcalRep package site for documentation and step-by-step tutorials/vignettes.

Installation

Firstly, please install or update the package devtools by running

install.packages("devtools")

Then the XcalRep can be installed via

library(devtools)
devtools::install_github(repo = "NMikolajewicz/XcalRep")
