Wrangling 'JDemetra+ 3.x' Workspace.

{rjd3workspace}

{rjd3workspace} offers several functions to wrangle JDemetra+ v3.x workspaces.

Seasonal adjustment with X-12ARIMA can be done with the package {rjd3x13} and with TRAMO-SEATS with the package {rjd3tramoseats}.

Installation

{rjd3workspace} relies on the {rJava} package

Running rjd3 packages requires Java 21 or higher. How to set up such a configuration in R is explained here

Latest release

To get the current stable version (from the latest release):

• From GitHub:

# install.packages("remotes")
remotes::install_github("rjdverse/rjd3workspace@*release")

• From r-universe:

install.packages("rjd3workspace", repos = c("https://rjdverse.r-universe.dev", "https://cloud.r-project.org"))

Development version

You can install the development version of {rjd3workspace} from GitHub with:

# install.packages("remotes")
remotes::install_github("rjdverse/rjd3workspace")

Usage

library("rjd3workspace")

dir <- tempdir()

y <- rjd3toolkit::ABS$X0.2.09.10.M
jws <- jws_new()
jsap1 <- jws_sap_new(jws, "sa1")
add_sa_item(jsap1, name = "x13", x = rjd3x13::x13(y))
add_sa_item(jsap1, name = "tramo", x = rjd3tramoseats::tramoseats(y))
save_workspace(jws, file.path(dir, "ws.xml"))

jws <- jws_open(file = file.path(dir, "ws.xml"))
jws_compute(jws) # to compute the models
jsap1 <- jws_sap(jws, idx = 1) # first SAProcessing
jsa1 <- jsap_sai(jsap1, idx = 1) # first SAItem
sai_name(jsa1)
#> [1] "x13"
mod1 <- read_sai(jsa1)

Create SA-item with path

# install.packages("remotes")
# remotes::install_github("rjdverse/rjd3providers")

dir <- tempdir()

xlsx_file <- file.path(system.file("extdata", package = "rjd3providers"), "Insee.xlsx")
ts1 <- rjd3providers::spreadsheet_series(file = xlsx_file, sheet = 1L, series = 3L)

y <- ts1$data
jws <- jws_new()
jsap1 <- jws_sap_new(jws, "sa1")
add_sa_item(jsap1, name = "x13", x = rjd3x13::x13(y))
set_ts(jsap = jsap1, idx = 1L, y = ts1)
add_sa_item(jsap1, name = "tramo", x = rjd3tramoseats::tramoseats(y))
set_ts(jsap = jsap1, idx = 2L, y = ts1)

save_workspace(jws, file.path(dir, "ws.xml"))

jws <- jws_open(file = file.path(dir, "ws.xml"))
jws_compute(jws) # to compute the models
jsap1 <- jws_sap(jws, idx = 1) # first SAProcessing
jsa1 <- jsap_sai(jsap1, idx = 1) # first SAItem
sai_name(jsa1)
#> [1] "x13"
mod1 <- read_sai(jsa1)

Change path of an SA-ITEM

xlsx_path <- normalizePath("data/IPI_nace4.xlsx", mustWork = TRUE)
csv_path <- normalizePath("data/IPI_nace4.csv", mustWork = TRUE)
ws_path <- normalizePath("WS/ws_industrie.xml", mustWork = TRUE)

jws <- .jws_open(file = ws_path)

# Update all the second SA-Processing with a new path
spreadsheet_update_path(
    jws = jws,
    new_path = xlsx_path,
    idx_sap = 2L
)

txt_update_path(
    jws = jws,
    new_path = csv_path,
    idx_sap = 1L
)

save_workspace(jws = jws, file = ws_path, replace = TRUE)
