metabdata: 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 log transformed metabolite levels and phenotype data of sample 115 of pregnant women. Metabolite levels are contained in columns 11-59, and missing values are indicated by NA. All metabolites included contain at least 5 missing values. Columns 1:10 represent phenotypic data.
