group_info_multiOmics

A data frame of grouping information for the samples in abundance_lipidOmics and abundance_rna, used for the multi-omics integration workflow (as_MultiAssayExperiment. Samples come from a hepatocellular carcinoma (HCC) cohort of 98 patients recruited between 2011 and 2013, and the group column ('tsne0'/'tsne1') divides the 59 patients with paired lipidomic and transcriptomic profiling into two subgroups based on t-SNE clustering of their lipidomic profiles.

Usage

data("group_info_multiOmics")

Format

A data frame with 59 observations on the following 4 variables.

sample_name

a character vector of de-identified sample IDs, matching the sample columns in abundance_lipidOmics and abundance_rna.

label_name

a character vector of sample labels (identical to sample_name for this dataset).

group

a character vector, one of 'tsne0' or 'tsne1', identifying which of the two t-SNE-derived lipidomic subgroups each sample belongs to.

pair

a logical vector. Not applicable for this (unpaired) dataset; all values are NA.
