Generate GMPL code to export all sets and parameters to CSV files

Creates GMPL printf statements that export all sets and parameters in a model to CSV files in a data_export/ directory using standard CSV format (comma-separated with headers). This code can be injected into a GMPL model file before the solve statement.

Usage

export_data_gmpl(
  model,
  export_dir = "data_export",
  drop_default_values = FALSE
)

Arguments

model: A model object with $sets and $parameters
export_dir: Directory name for exports (default: "data_export")
drop_default_values: logical; if TRUE, exclude values that match the default (default: FALSE)

Value

Character string with GMPL export statements

Examples

if (FALSE) { # \dontrun{
model <- read_gmpl("model.mod", "data.dat")
export_code <- export_data_gmpl(model)
cat(export_code)
} # }
