The R-package persephone was developed to enable easy processing of multiple time series during the production of seasonally adjusted estimates. It will be used as a successor of the R package x12 which is still used at Statistics Austria, but faded out in some projects already. RJDemetra, an R interface to JDemetra+ (https://github.com/jdemetra) is used to perform the seasonal adjustment. Additionally, analytic tools such as interactive plots are developed to support the SA expert. These tools makes it easy to construct personalized dashboards containing selected plots and diagnostics and to produce a Eurostat-Quality-Report.
