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

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
