Read a GMPL data file and populate a multimod model's sets and parameters. This is more efficient for large models as it directly populates the model and can save to CSV/arrow format.
Usage
import_gmpl_data(
model,
gmpl_data,
model_path = NULL,
format = c("memory", "csv", "arrow"),
verbose = FALSE
)Arguments
- model
A multimod model object
- gmpl_data
Path to GMPL data file, character vector of data file contents, or a list from read_gmpl_data()
- model_path
Optional path to save parameter data as CSV files (default: model's base_path)
- format
Data storage format: "memory" (default), "csv", or "arrow"
- verbose
Logical. If TRUE, print progress (default FALSE)
Examples
if (FALSE) { # \dontrun{
# Read model structure
model <- read_gmpl("osemosys.txt", as_multimod = TRUE)
# Import data from file
model <- import_gmpl_data(model, gmpl_data = "utopia.txt")
# Import from character vector (e.g., package data)
data(example_models)
model <- import_gmpl_data(model, gmpl_data = example_models$OSeMOSYS$gmpl$data)
# Or import pre-parsed data
data <- read_gmpl_data("utopia.txt")
model <- import_gmpl_data(model, gmpl_data = data)
# Save to specific directory as CSV
model <- import_gmpl_data(model, gmpl_data = "utopia.txt",
model_path = "path/to/model/data",
format = "csv")
} # }
