Updates to repmis: caching downloaded data and Excel data downloading

Over the past few months I’ve added a few improvements to the repmis–miscellaneous functions for reproducible research–R package. I just want to briefly highlight two of them:Caching downloaded data sets.source_XlsxData for downloading data in Excel formatted files.Both of these capabilities are in repmis version 0.2.9 and greater.CachingWhen working with data sourced directly from the internet, it can be time consuming (and make the data hoster angry) to repeatedly download the data.

A few weeks ago on this blog Andrea Römmele and Yann Lorenz argued that the current election cycle has been characterised by personality politics between candidates vying for the Commission presidency, rather than substantive issues.However, the election campaigns could be an important opportunity for the public to express their views on and even learn more about one of the defining changes to the European Union since the introduction of the Euro: the European Banking Union.Much of the framework for the Banking Union has been established in the past year after intense debate between the EU institutions.
