Create Predictor Data Table — pred_data

Construct and validate a pred_data_t objects, which are used to store predictor data. Different data types (float, int, bool) have different subclasses (pred_data_t_float, ...)

Usage

as_pred_data_t(x, type)

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

Arguments

x: Coercible to data.table
type: Character string specifying the data type: "float", "int", or "bool"
nrow: see data.table::print.data.table
...: passed to data.table::print.data.table

Value

A data.table of class "pred_data_t_" and "pred_data_t" with columns:

id_pred: Foreign key to pred_meta_t
id_coord: Foreign key to coords_t
id_period: Foreign key to periods_t
value: Predictor value (type depends on subclass)

Methods (by generic)

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