Plot splitdot plot

Plot splitdot plot

plot_splitdot(
  enrichment,
  topN = NA,
  mode = "gene_ratio",
  show_signif_overlay = TRUE
)

Arguments

enrichment

GOAT enrichment result, pre-sorted in the desired display order (top row appears at top of plot)

topN

default: NA to plot all, else integer to plot topN terms (first N rows)

mode

Character. Either "gene_ratio" (default) or "pvalue". Controls x-axis and color legend only; row order is taken from the input data. "gene_ratio": x = GeneRatio, color = adjusted p-value. "pvalue": x = adjusted p-value, color = GeneRatio.

show_signif_overlay

Logical. When TRUE, adds an inner black dot representing ngenes_signif on the same size scale as ngenes. Default: TRUE.

Value

ggplot2 object. attr(p, "suggested_width") contains a suggested render width in inches based on the longest term label — pass to ggsave(width = ...) or renderPlot(width = ... * 96) in Shiny.
