In DanielQuiroz97/RGCxGC: Preprocessing and Multivariate Analysis of Bidimensional Gas Chromatography Data

Join multiple two-dimensional chromatograms into a single R object

Description

'join_chromatograms' saves chromatograms in a named list slot. Also, it saves information like metadata and retention times.

Usage

join_chromatograms(x, y, groups, ...)

Arguments

x, y	a GCxGC object, either single or batch chromatograms.
groups	a data.frame containing the metadata. It must have a column named as Names to merge with the imported chromatograms.
...	other GCxGC objects to be merged

Examples

GB08_fl <- system.file("extdata", "08GB.cdf", package = "RGCxGC")
GB09_fl <- system.file("extdata", "09GB.cdf", package = "RGCxGC")
GB08 <- read_chrom(GB08_fl, 5L)
GB09 <- read_chrom(GB09_fl, 5L)
join_gc <- join_chromatograms(GB08, GB09)
metadata <- data.frame(Names = c("GB08", "GB09"),
                       Type = c("Control", "Treatment"))
join_metadata <- join_chromatograms(GB08, GB09, groups = metadata)
