Metabolite set enrichment analysis for loadings

mseapca provides functions for metabolite set enrichment analysis with loading in principal component anaysis and partial least squares, and single sample enrichment analysis.

• Metabolite set enrichment analysis [1] can be performed using the “msea_ora” or “msea_sub” functions.

• Our mseapca package utilizes the loadings package ( https://cran.r-project.org/web/packages/loadings ) to conduct multivariate analyses like PCA and PLS, along with their respective loadings.

• The “ssea_ora” function can be used to compute single sample enrichment analysis based on over-representation analysis [2].

• Our mseapca package can incorporate a metabolite set list from the PathBank database by referencing the AHPathbankDbs Bioconductor package or through user-generated lists.
