Select genes with the highest variance across samples.
Usage
genes_top_variance(phyex_set, p = 0.99)
Arguments
- phyex_set
A PhyloExpressionSet object
- p
Quantile threshold for gene selection (default: 0.99)
Value
Character vector of gene IDs with variance >= p quantile
Details
This function identifies genes with the highest variance across samples,
which are often the most informative for downstream analyses.
Examples
# Select top 1% most variable genes
# high_var_genes <- genes_top_variance(phyex_set, p = 0.99)
