euMetabData: A sample data set of truncated metabolomics data.

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

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("euMetabData")

Format

A data frame with 120 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 120 rows correspond to mother / baby sample triples of analytical interest. 24 of these samples were run in each batch. Row names ending in "_mf" are for fasting maternal samples. Row names ending in "_m1" are for maternal samples at 1-hour into an oral glucose tolerance test. Row names ending in "_bc" are for samples of baby cord blood collected at birth.
