Characterising and understanding how human phenotypes relates to populations requires being able to count the occurrence of certain traits in individuals from different populations. Using NMR and MS based metabolic profiles, this means being able to estimate the presence of a feature, aka a signal, across the whole dataset aggregate ...

We have recently published a strategy for improving human metabolic phenotyping using Combined Multiblock Principal components Analysis with Statistical Spectroscopy (COMPASS). The COMPASS approach is developed within R environment. The open access manuscript can be found here.

Interactive data visualization is a must to develop attractive tools for a broad audience. Here I will show how to use a JavaScript framework to visualize results computed with R. I think it is a good idea to keep computation separated from visualization to make more robust pipelines, hence the ...
