Function to extract ground-truth from attractor-based simulation made with the function attractor_simulation

This function extracts the ground-truth values for functional spatial effect values, replicate random effect values, and indicators for spatially variable genes (SVGs) and genes with functional spatial effects (FSEs) from a simulation object created by the attractor_simulation function.

Usage

attractor_simulation_ground_truth(sim)

Arguments

sim

A list object returned by the attractor_simulation function, containing the simulation data and parameters.

Value

A list containing the following components: fse_true, ran_true, SVGs, and FSEs.

Examples

set.seed(1)
toy_seed <- data.frame(
  gene    = rep(c("geneA", "geneB"), each = 20),
  coord_x = runif(40, 0, 10),
  coord_y = runif(40, 0, 10),
  count   = rpois(40, 5)
)
sim <- attractor_simulation(toy_seed, n_bins = 5, n_replicates = 2)
truth <- attractor_simulation_ground_truth(sim)
truth$SVGs
#> geneA geneB 
#>  TRUE  TRUE
