Save an eim object to a file

Description

This function saves an eim object to a specified file format. Supported formats are RDS, JSON, and CSV. The function dynamically extracts and saves all available attributes when exporting to JSON. If the prob field exists, it is saved when using CSV; otherwise, it yields an error.

Usage

save_eim(object, filename, ...)

Arguments

object	An eim object.
filename	A character string specifying the file path, including the desired file extension (.rds, .json, or .csv).
...	Additional arguments (currently unused but included for compatibility).

Details

• If the file extension is RDS, the entire object is saved using saveRDS().

• If the file extension is JSON, all available attributes of the object are stored in JSON format.

• If the file extension is CSV:

  • If the object contains a prob field, only that field is saved as a CSV.

  • Otherwise, returns an error.

Value

The function does not return anything explicitly but saves the object to the specified file.

Examples

model <- eim(X = matrix(1:9, 3, 3), W = matrix(1:9, 3, 3))

model <- run_em(model)

td <- tempdir()
out_rds <- file.path(td, "model_results.rds")
out_json <- file.path(td, "model_results.json")
out_csv <- file.path(td, "model_results.csv")

# Save as RDS
save_eim(model, filename = out_rds)

# Save as JSON
save_eim(model, filename = out_json)

# Save as CSV
save_eim(model, filename = out_csv)

# Remove the files
files <- c(out_rds, out_json, out_csv)
file.remove(files)
