I am starting analysis of metabolomics data.
I want to use R only for the statistical analysis of the raw matrix: I mean normalization, pca , clustering, missing value imputation anova ....
As I first approach since I am coming from microarray I am thinking to produce an expressionset and use my scripts for the arrays.
Any suggestion? I have seen the metabolomics packages in bioconductor and I am not so enthusiastic but maybe I have to spend more time learning about them.
Thanks for any suggestion
