metabCombiner

This is an R package for aligning a pair of disparately-acquired untargeted LC-MS metabolomics. metabCombiner takes peak-picked and conventionally aligned untargeted LC-MS datasets and determines the overlapping <mass-to-charge (m/z), retention time (rt)> features, concatenating their measurements to form a combined table of sample mass spectral measurements.

installation

#for R versions 4.0 and later
devtools::install_github("hhabra/metabCombiner", build_vignettes = TRUE)
library(metabCombiner)

#for R versions between 3.5 and 4
devtools::install_github("hhabra/metabCombiner", build_vignettes = TRUE, ref = "R3.5")

How to Use metabCombiner

In the /demo directory, we have an example R script showing a demonstration of the package's utilities. See the vignette by entering browseVignettes("metabCombiner") for a more detailed description of how to use metabCombiner.
