Plot Simulated Features by Ancestry and Group (base R + data.table) — plot_simulated

Visualize expression of selected genes from simulated data, grouped by ancestry and filled by group.

Usage

plot_simulated_features(
  sim_data,
  features = NULL,
  a_col = "ancestry",
  g_col = "group",
  zscore = TRUE,
  n = 12,
  seed = NULL
)

sim_data: Output from `simulate_DEG_signal()` or `simulate_NB_counts()`.
features: Optional character vector of gene names to plot. If NULL, samples `n` genes.
a_col: Column in `sample_info` used for x-axis grouping (e.g., "ancestry").
g_col: Column in `sample_info` used for fill color (e.g., "group").
zscore: Logical. If TRUE, z-score normalize each gene across samples.
n: Number of genes to sample if `features` is NULL.
seed: Optional random seed.

A ggplot2 object showing boxplots for selected features.
