The metaXpressResult class

Holds the output of a meta-analysis performed by mx_meta, including gene-level statistics, heterogeneity estimates, and (optionally) pathway enrichment results.

Slots

meta_table

A data.frame with one row per gene. Required columns: gene_id, meta_log2FC, meta_pvalue, meta_padj, i_squared, q_stat, n_studies, direction_consistency.

method

A length-1 character naming the meta-analysis method used. One of "random_effects", "fixed_effects", "fisher", "stouffer", "inverse_normal", "minp", "maxp", "rop".

n_studies

A length-1 integer giving the total number of studies integrated.

heterogeneity

A data.frame with per-gene heterogeneity statistics: gene_id, Q, df, I_sq, tau_sq, p_heterogeneity.

pathway_result

A data.frame of pathway meta-analysis results. Empty until mx_pathway_meta is called.
