Save and load aggregated isofile data

Source: R/storage.R
ir_storage.Rd

ir_save_aggregated_data() serializes an ir_aggregate_isofiles() result to a parquet file. Empty datasets (no columns) are dropped. The condition column of problems is set to NULL per row because R condition objects cannot be stored in parquet. ir_load_aggregated_data() reads the file back and returns an ir_aggregated_data object.

Usage

ir_save_aggregated_data(aggregated_data, file)

ir_load_aggregated_data(file)

Arguments

aggregated_data

datasets aggregated from ir_aggregate_isofiles()

file

path to the parquet file (.parquet extension added if absent)

Value

ir_save_aggregated_data() returns aggregated_data invisibly; ir_load_aggregated_data() returns an ir_aggregated_data object.

Details

Requires the arrow package (suggested). If not installed, one installation attempt from CRAN is made automatically.
