The new version of our rOpenGov R package regions was released today on CRAN. This package is one of the engines of our experimental open data-as-service Green Deal Data Observatory, Economy Data Observatory, and Digital Music Observatory prototypes, which aim to place open data packages into open-source applications.
In international comparison the use of nationally aggregated indicators often have many disadvantages: they inhibit very different levels of homogeneity, and data is often very limited in number of observations for a cross-sectional analysis. When comparing European countries, a few missing cases can limit the cross-section of countries to around 20 cases which disallows the use of many analytical methods.
Working with sub-national statistics has many advantages: the similarity of the aggregation level and high number of observations can allow more precise control of model parameters and errors, and the number of observations grows from 20 to 200-300.
Yet the change from national to sub-national level comes with a huge data processing price. While national boundaries are relatively stable, with only a handful of changes in each recent decade, the change of national boundaries requires a more-or-less global consensus. But states are free to change their internal administrative boundaries, and they do it with high frequency. This means that the names, identification codes and boundary definitions of sub-national regions change very frequently. Joining data from different sources and different years can therefore be very difficult.
There are numerous advantages in switching from a national level of the analysis to a sub-national level. This, however, requires more effort in data processing, validation and imputation. Our regions package aims to help in this process.
You can review the problem, and the code that created the two map comparisons, in the Mapping Regional Data, Mapping Metadata Problems vignette article of the package. A more detailed problem description can be found in the Working With Regional, Sub-National Statistical Products vignette.
This package is an offspring of the eurostat package on rOpenGov. It started as a tool to validate and re-code regional Eurostat statistics, but it aims to be a general solution for all sub-national statistics. It will be developed parallel with other rOpenGov packages.
