In mnodzenski/metabomxtr: A package to run mixture models for truncated metabolomics data with normal or lognormal distributions

A sample data set of truncated metabolomics data.

Description

This data set contains a subset of non-targeted GC/MS data for mother / baby pairs of Northern European ancestry who participated in the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Metabolomics study.

Usage

data("euMetabCData")

Format

A data frame with 30 observations on the following 6 variables.

batch

A factor variable for the batch in which the sample was processed with levels 1 2 3 4 5.

pheno

A factor variable indicating whether the serum sample was from a mother or baby with levels BABY MOM.

betahydroxybutyrate

A numeric vector of non-normalized GC/MS log2 transformed peak areas for this metabolite.

pyruvic_acid

A numeric vector of non-normalized GC/MS log2 transformed peak areas for this metabolite.

malonic_acid

A numeric vector of non-normalized GC/MS log2 transformed peak areas for this metabolite.

aspartic_acid

A numeric vector of non-normalized GC/MS log2 transformed peak areas for this metabolite.

Details

The 30 rows correspond to 3 mom and 3 baby control samples run at the beginning, middle and end of each batch. All control samples were drawn from an identical pool.
