Convert 'RJDemetra' (v2) Objects to 'rjd3' (v3) Format

Converts seasonal adjustment models, outputs, or specification objects from legacy 'RJDemetra' ('JDemetra+' v2) to the modern 'rjd3' ecosystem (such as packages rjd3x13 or rjd3tramoseats for 'JDemetra+' v3).

Usage

as_rjd3(x, new_spec = NULL, ...)

# S3 method for class 'SA_spec'
as_rjd3(x, new_spec = NULL, ...)

# S3 method for class 'regarima'
as_rjd3(x, new_spec = NULL, ...)

# S3 method for class 'SA'
as_rjd3(x, new_spec = NULL, ...)

# S3 method for class 'regarima_spec'
as_rjd3(x, new_spec = NULL, ...)

Arguments

x

An object from the 'RJDemetra' package (v2, e.g., of class SA, SA_spec).

new_spec

An optional specification object from the 'rjd3' ecosystem (v3) to be used as a base for conversion. If NULL, a default specification will be created based on the type of model being converted.

...

Additional arguments passed to specific methods.

Value

An equivalent object compatible with the 'rjd3' ecosystem (v3 structure).

A list with two elements:

• context: An object of class rjd3toolkit::modelling_context() containing any user-defined variables.

• result: The converted object in the 'rjd3' format.

Details

The parameters ub1 and ub2 are not translated since it seems to have a different convention between versions.

Examples

# Convert only a specification object
spec_v2 <- RJDemetra::regarima_spec_tramoseats()
spec_v3 <- as_rjd3(spec_v2)

# \donttest{
# Convert a full seasonal adjustment model
y <- RJDemetra::ipi_c_eu[, "FR"]
model_v2 <- RJDemetra::x13(y, spec = "RSA5c")
model_v3 <- as_rjd3(model_v2)
# }
