Create parameter grid for job submission

Generate a grid of parameter combinations for parameter sweeps, compatible with slurm_pmap for parallel execution.

Usage

grid(..., .filter = NULL, .add_metadata = TRUE)

Arguments

...

Named arguments with vectors of values to expand

.filter

Optional function to filter combinations

.add_metadata

Whether to add metadata columns

Value

Data frame with one row per parameter combination

Examples

# \donttest{
# Simple parameter grid
params <- grid(
  alpha = c(0.1, 0.5, 1.0),
  beta = c(1, 2),
  method = c("lm", "glm")
)
# Creates 3 * 2 * 2 = 12 combinations

# With filtering
params <- grid(
  x = 1:3,
  y = 1:3,
  .filter = ~ .x <= .y  # Only upper triangle
)

# Use with slurm_pmap (local engine for examples)
if (interactive()) {
  jobs <- slurm_pmap(params, function(x, y, method, ...) {
    # Run analysis with these parameters
    x + y
  }, .engine = "local")
}
# }
