Arguments

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

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.
