The goal of rjwsacruncher is to launch quickly and easily the JWSACruncher of JDemetra+. The JWSACruncher is a console tool that allows to update a JDemetra+ workspace and to export the results without having to open JDemetra+. More details on the JWSACruncher can be found on https://github.com/jdemetra/jwsacruncher/wiki.
# Install release version from CRAN
install.packages("rjwsacruncher")
# Install development version from GitHub
# install.packages("devtools")
devtools::install_github("AQLT/rjwsacruncher")The JWSACruncher is not included in the package. It can be downloaded from GitHub (https://github.com/jdemetra/jwsacruncher/releases) or with the function download_cruncher():
library(rjwsacruncher)
# Directory where to save the JWSACruncher:
directory <- tempdir()
download_cruncher(directory)Since the version 2.2.0, the JWSACruncher needs Java 8 or higher to run. If you cannot install it (for example for security reasons) you can install a portable version of ‘Java’ (that does not require administrator rights) and configure the JWSACruncher to use this portable version with the function configure_jwsacruncher().
The JWSACruncher can be easily runned with the function cruncher_and_param(). To use it, the path to the “Bin” folder of the JWSACruncher has to be defined. For example, if the JWSACruncher is under D:/jdemetra-cli-2.2.3/:
The export items can be changed with the function “default_matrix_item” and “default_tsmatrix_series”:
# To get the default values:
head(getOption("default_matrix_item"))
#> [1] "period" "span.start" "span.end" "span.n" "span.missing"
#> [6] "espan.start"
getOption("default_tsmatrix_series")
#> [1] "y" "t" "sa" "s" "i" "ycal"
# To only export the seasonally adjusted series and its forecasts:
options(default_tsmatrix_series = c("sa", "sa_f"))The run the JWSACruncher on the workspace D:/workspace.xml with the refresh policy “lastoutliers”:
