save_round: Save, load, and list forecast rounds

In qpmR: Quarterly Projection Models for Monetary Policy Analysis

Save, load, and list forecast rounds

Description

A round store is a plain directory: each round lives in ⁠store/<slug>/⁠ as a self-contained round.rds plus human-readable sidecars (forecast.csv, data.csv, calibration.csv, and judgment.csv when judgment was applied) so that a round can be audited without R.

Usage

save_round(round, store, overwrite = FALSE)

load_round(name, store = "rounds")

list_rounds(store = "rounds")

Arguments

round	A qpm_round.
store	Directory of the round store. save_round() creates it if missing and has no default, so nothing is written unless you name the location; the reading functions default to a "rounds" directory under the working directory.
overwrite	Allow replacing an existing round of the same name.
name	Round name (or its slug), or a direct path to a round directory or round.rds.

Value

save_round() returns the round directory invisibly; load_round() returns the qpm_round; list_rounds() returns a data frame of the store's contents.

Examples

m <- qpm_template("bkl")
obs <- simulate(qpm_solve(m), nsim = 40, seed = 1, burn = 20)
obs$period <- next_quarters("2016-Q1", 40)
r <- qpm_round("demo", m, obs[, c("period", "pi", "i", "q")], horizon = 8)
store <- file.path(tempdir(), "rounds")
save_round(r, store)
list_rounds(store)
r2 <- load_round("demo", store)
