Spirometry equations for R

rspiro - Spirometry equations for R

Package rspiro implements multiple spirometry equations: currently the GLI-2012 (Quanjer) and NHANES III (Hankinson), with potentially more to be added later.

It offers user-friendly functions to calculate predicted or LLN (Lower Limit of Normal) values given demographic data, or to convert absolute spirometry values to percent (%) predicted or z-scores.

Installation

Open R, and give:

  devtools::install_github("thlytras/rspiro")

If you do not have the package "devtools", first install it from CRAN with:

  install.packages("devtools")

Acknowledgement

This package uses the lookup tables provided by the GLI initiative, to whom I'm grateful for their work.
