R-CMD-check CRAN CRAN-checks Codecov test coverage Downloads-weekly Downloads-total DOI DOI

This project downloads a set of shapefiles relevant to the Czech Republic. It was inspired by the popular tigris package for US datasets.

Kraje České republiky

For examples of RCzechia in action please see the package vignette:

The administrative area polygons are based on the RÚIAN register; the natural objects were based originally on ArcČR 500 by ARCDATA and later moved to Data200 by ČÚZK.

The shapefiles are by necessity larger than the limits of a CRAN package size allow. The data are therefore stored remotely (on Amazon Cloud / AWS S3) and downloaded as required. As consequence a working internet connection is required to fully use the package.

For the most commonly used shapes (republika, kraje and okresy) an optional low resolution version is also included. To access it specify the value of resolution parameter as "low" (default is "high").

Access to the external files is logged, from time to time I check the logs (mainly to better understand my bandwidth charges).

A note to Czech users

Tohle je “oficiální”, a tedy anglické, readme. Českou verzi naleznete na http://www.jla-data.net/cze/package-rczechia/


The package is on CRAN (as of March 2018) so to get a stable version simply run:


You can also get the latest development version by running remotes::install_github("jlacko/RCzechia"). The main branch should be always reasonably stable, but I do not suggest cloning of development branches unless you know what you are doing - these are where the raw action is happening, red in tooth and claw.

The following spatial objects are included:



All objects are implemented as functions returning data frames, so must be followed by brackets (i.e. hranice <- republika()).

In addition a number of utility functions is provided:

Call for Action

The project is actively maintained, and ideas & suggestions to improve the package are greatly welcome. Should you feel more at ease with old fashioned email than the GitHub ticketing system - do drop me a line.

But raising an issue is preferable, as I am human and I forget; GitHub does not suffer from such a failing, and will keep on reminding me till the sun and moon are darkened, and the stars no longer shine.

More detailed information can be found in the CONTRIBUTING document.
