Plot fold-change barplots across comparisons for selected genes

Usage

get_foldchange_barplot(
  x,
  genes,
  sample_comparisons = NULL,
  facet = TRUE,
  coord_flip = FALSE,
  display_id = NULL,
  sort_by = c("input", "log2fc", "abs_log2fc"),
  facet_comparison = FALSE,
  facet_scales = "free_y"
)

Arguments

x: A VISTA object containing differential expression results.
genes: Character vector of gene IDs to plot.
sample_comparisons: Optional character vector of comparison names to include; defaults to all available.
facet: Logical; facet by gene when TRUE.
coord_flip: Logical; flip axes when TRUE.
display_id: Optional column in rowData(x) to use for gene labels. Input gene matching still uses gene_id.
sort_by: How to order genes when faceting: "input" (use supplied order), "log2fc" (descending log2FC of the first comparison), or "abs_log2fc" (descending max absolute log2FC across comparisons).
facet_comparison: Logical; facet by comparison (x = gene) instead of faceting by gene (x = comparison).
facet_scales: Facet scales argument passed to facet_wrap() when faceting (default "free_y").
