add_variables: Add a Variable to a JD+ Workspace

In rjd3workspace: Wrangling 'JDemetra+ 3.x' Workspaces

Add a Variable to a JD+ Workspace

Description

Adds a single time series variable to a specified group within a JD+ workspace..

Usage

add_variables(jws, group, name, y, overwrite = FALSE)

Arguments

jws	A JD+ workspace object (Java pointer).
group	A character string indicating the name of the group in which to store the variable.
name	A character string naming the variable.
y	A ts object (R time series) to be added. Only a single time series can be added at a time.
overwrite	a Boolean to indicate whether a variable already present should be replaced

Details

For the time being, if the group does not already exist, a new group is created, but the group will be named after name, not group.

Value

No return value (NULL returned invisibly). This function is used for its side effect of modifying the workspace.

Limitations

• Cannot add multiple variables at once.

• Does not support dynamic ts objects with metadata.

• If group does not exist, a new group is created but named after the variable name, not the intended group.

See Also

rjd3toolkit::modelling_context() to create multiple variables and groups at once, and read_variables(), write_variables() to import/export variables.

Examples

# Load a Workspace
file <- system.file("workspaces", "workspace_test.xml", package = "rjd3workspace")

jws <- jws_open(file)
add_variables(jws = jws, group = "reg1", y = AirPassengers, name = "x1")
