Build Status CRAN_Status_Badge

GCalignR provides simple functions to align peak lists obtained from Gas Chromatography Flame Ionization Detectors (GC-FID) based on retention times and plots to evaluate the quality of the alignment. The package supports any other one-dimensional chromatograpy technique that enables the user to create a peak list with at least one column specifying retention times as illustrated below.

Installing GCalignR:

install.packages("GCalignR", dependencies = T)
    if (!("devtools" %in% rownames(installed.packages()))) { 
    } else if (packageVersion("devtools") < 1.6) {
    devtools::install_github("mottensmann/GCalignR@v1.0.1-beta", build_vignettes = TRUE)
