This package is an object oriented wrapper around the R Package RJDemetra, which performs time series adjustments with the java library JDemetra+
# install the package from GitHub
devtools::install_github("statistikat/persephone")
# optional: also install vignettes (needs prettydoc)
devtools::install_github("statistikat/persephone", build_vignettes = TRUE)
Objects can be constructed with perX13
or perTramo
. Subseqentually, the run
method runs the model and output
gives access to the output object from RJDemetra
.
library(persephone)
obj <- perX13(AirPassengers)
plot(obj)
The original output from RJDemetra can be inspected via the output
field.
