[R] Searching for packages for normalizing Metabolomic data
Hi everybody, I am a beginner in the steps of pre-processing and data analysis of non-targeted metabolomic profiling experiments. Anyone knows if there exists some tool for normalizing this type of data (raw data or XCMS matrix data) in R repositories? Many thanks in advance.

Many thanks in advance.Bioconductor has several packages that might be appropriate, e.g., xcms.
