The goal of RGCxGC is to provide an easy-to-use platform to analyze two-dimensional gas chromatography data. RGCxGC offers common pre-processing algorithms for signal enhancement, such as baseline correction based on asymetric least squares, smoothing based on the Whittaker smoother, and peak alignment 2D COW. Furthermore, the multiway principal component analysis is implemented based on the Wold’s approach.
