exhaustive_ratios: Exhaustive Ratios

In vladpetyuk/vp.misc: Miscellaneous functions used by Vlad Petyuk for proteomics data analysis

Description

For a group of features size N it exhaustively generates N*(N-1)/2 ratios and returns another MSnSet.

Usage

exhaustive_ratios(m, INDEX = NULL)

Arguments

m	MSnSet object
INDEX	character Name of one of the columns in fData(m). If NULL (defaults), then ratios generated assuming all features (e.g. peptides or proteforms) belong to one grouping factor.

Details

There are few scenarios when this function can be useful.

• SRM data. Generate full exhaustive ratios to normalized per tissue leakage.

• Top-Down data. Generate ratios of proteoforms within a given gene.

• any data. Ratios within a given pathway to assess dysregulation.
