Create a boxplot showing the distribution of expression levels
for each phylostratum.
Usage
plot_strata_expression(phyex_set, aggregate_FUN = mean)
Arguments
- phyex_set
A PhyloExpressionSet object (BulkPhyloExpressionSet or ScPhyloExpressionSet)
- aggregate_FUN
Function to aggregate expression across identities (default: mean)
Value
A ggplot2 object showing expression distributions by phylostratum
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(bulk_phyex_set, aggregate_FUN = mean)
# Plot using median aggregation for single-cell data
# p2 <- plot_strata_expression(sc_phyex_set, aggregate_FUN = median)
