plot_strata_expression: Plot Expression Levels by Phylostratum

Description

Create a boxplot showing the distribution of expression levels for each phylostratum.

Usage

plot_strata_expression(phyex_set, aggregate_FUN = mean)

Value

A ggplot2 object showing expression distributions by phylostratum

Arguments

phyex_set

A PhyloExpressionSet object (BulkPhyloExpressionSet or ScPhyloExpressionSet)

aggregate_FUN

Function to aggregate expression across identities (default: mean)

Details

This function creates a boxplot visualization showing how expression levels vary across different phylostrata. Each point represents a gene, and the boxes show the distribution of expression levels within each phylostratum.

For bulk data, expression is aggregated across developmental stages. For single-cell data, expression is aggregated across cell types.

Examples

# Plot expression by strata using mean aggregation for bulk data
p1 <- plot_strata_expression(example_phyex_set, aggregate_FUN = mean)

# Plot using median aggregation for single-cell data
p2 <- plot_strata_expression(example_phyex_set_sc, aggregate_FUN = median)
