R help - Dec 2010 - 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.
 
 
 
Best regards,
 
 
 
Núria

Bioconductor has several packages that might be appropriate, e.g., xcms.
