RCzechia - May 2020 release

Most administrative units are based on RÚIAN polygons (as of 31st March 2020) as opposed to original ARC ČR 500 data.

This allows smaller objects, and faster downloads, without sacrificing too much in terms of quality.

In addition new object - rivers in city - was added, and internal data was aligned with PROJ >= 6.0.0 structures

RCzechia - First CRAN release

The package was accepted on CRAN. In order to pass the package size limits all data sets were converted from local (internal storage) to external (stored on Amazon S3).

A working internet connection is therefore required to use the package. All object names, structure and contents are unchanged, but data frames were replaced by functions (returning data frames) - remember to use empty brackets when calling them.

Package byla přijata na CRAN. Abych se vešel do limitů velikosti, musel jsem všechny objekty změnit z interních (uvnitř package) na externí (stahované z Amazon S3).

Pro používání package je proto potřeba fungující internetové připojení. Názvy objektů, struktura ani obsah se nemění, ale místo data framů jsou funkce (vracející data frame) - je potřeba za nimi uvádět prázdné závorky.
