Create Runs Table — runs

Creates a runs_t table that stores the identities, hierarchy, and description of runs. Defaults to a table with one row with the base id_run := 0. Runs are a feature that allows one to label data that is either overriding base data (e.g. predictors being used for forecasting) or produced by a specific model experiment (e.g. a given allocation of land use change given a set of transition potential models and allocation parameters).

Usage

as_runs_t(x)

# S3 method for class 'runs_t'
print(x, nrow = 10, ...)

db_active_id_run(self, private, x)

Arguments

x: A list or data.frame coercible to a data.table
nrow: see data.table::print.data.table
...: passed to data.table::print.data.table

Value

A data.table of class "runs_t" with columns:

id_run: Foreign key to runs_t
id_period: Foreign key to periods_t
id_trans: Foreign key to trans_meta_t
rate: Transition rate (0 to 1)

Methods (by generic)

print(runs_t): Print a runs_t object, passing params to data.table print

Functions

db_active_id_run(): Get or set the active run ID; error if no lineage is found
