Pie chart of DEG counts (Up/Down) across comparisons

Usage

get_deg_count_pieplot(
  x,
  sample_comparisons = NULL,
  label_type = c("both", "count", "percent", "none"),
  label_digits = 1,
  base_size = 12,
  colors = c(Up = "red4", Down = "blue4"),
  show_other = FALSE,
  other_color = "grey70",
  text_color = "black",
  facet_by = c("comparison", "none"),
  ncol = NULL,
  label = NULL
)

Arguments

x: A VISTA object containing DEG summaries.
sample_comparisons: Optional character vector of comparison names to display.
label_type: Label content: "both", "count", "percent" or "none".
label_digits: Integer number of decimals used for percentage labels.
base_size: Numeric base font size for the plot.
colors: Named vector giving fill colors for "Up" and "Down" slices. When show_other = TRUE, an "Other" entry may also be supplied.
show_other: Logical; when TRUE, include non-DE genes as an "Other" slice using other_color unless overridden in colors.
other_color: Fill colour used for the "Other" slice when show_other = TRUE and colors does not include "Other".
text_color: Colour used for pie label text.
facet_by: Either "comparison" (default) to draw one pie per comparison, or "none" for a single pie.
ncol: Optional number of columns when faceting.
label: Deprecated; use label_type. TRUE/FALSE map to "both"/"none".

Value

A ggplot2 object drawing DEG counts as a pie chart.

Examples

v <- example_vista()
p <- get_deg_count_pieplot(v)
print(p)
