Initial release of the package, development can be seen at https://github.com/brry/rdwd/compare/master@{2016-10-19}...master@{2017-01-24} - selectDWD: uses index information to find files matching a path or station criteria. - With the returned path/file names, dataDWD and readDWD download and read data. - dirDWD and fileDWD: control that no file will be overwritten and path messages are useful. - indexDWD: lists all the files on the FTP server with DWD data. - createIndex: uses that list to create fileIndex, metaIndex and geoIndex. - mapDWD: is an interactive leaflet map also useful to explore datasets.

Note: dataDWD and readDWD were started in June 2016 within my misc package berryFunctions, from which they will be deleted after rdwd is on CRAN
