statnipokladna

The goal of statnipokladna is to provide programmatic access to open data from the Státní pokladna system. Státní pokladna is a comprehensive budgeting, reporting and accounting system for Czech public organisations. This package provides user-friendly ways to access the open data from that system available at https://monitor.statnipokladna.cz. The vignettes in the package also provide an introduction to the underlying data.

Installation

You can install the released version from CRAN:

install.packages("statnipokladna")

You can install the current development release of statnipokladna from GitHub with:

remotes::install_github("petrbouchal/statnipokladna",
                        build_vignettes = TRUE,
                        ref = github_release())

or the latest in-development version with

remotes::install_github("petrbouchal/statnipokladna",
                         build_vignettes = TRUE)

I also keep binaries in a drat repo, which you can access by

install.packages("statnipokladna", repos = "https://petrbouchal.github.io/drat")

Bug reports

Please report bugs at https://github.com/petrbouchal/statnipokladna/issues.

What this package enables you to do:

get cleaned-up, ready to analyse data frames based on open data dumps from the public finance database
- the package draws on the online data and returns a clean data frame
- the resulting data is ready to merge into time series
- time series is built based on user input
do this through a consistent API which supplements some of the documentation that is missing from the official endpoints (still subject to some change)
access registers published alongside the data (e.g. lists of public organisations with their identifiers and metadata), some of which can be useful in other contexts
augment the core data with the desired type of register

See the Get started vignette for background on the underlying data.

How does this compare to the official analytical interface?

no limit on the number of data points
no limits on the number of organisations, unlike the official interface which forces you to use a filter on some tables
different reports (local gov, central gov…) in one place in consistent form
much faster for analysis (the current version of the online interface takes long to render)
reproducible!!! While the online interface provides a permanent link to your analysis, this must be copied manually and does not necessarily provide an easily legible overview of how the analysis was produced (filters, columns etc.)
no need for the web => excel => R dance
drawback: for some reports, the data is published in different forms for different time periods (pre- and post-2015)
drawback: consolidation must be done manually

Future development

the official system has been partially overhauled in February 2020 and I am trying to find out about which parts of its new API will remain stable and can be used externally. Depending on the result, some functionality in this package can be streamlined and some can be added - e.g.

listing of available releases
checking against existing releases and data sets
retrieving some previously unpublished data e.g. calculated indicators and budget responsibility monitoring

Getting started

library(statnipokladna)

Get data from a particular part (file) of a dataset (“výkaz”):

local_budgets <- sp_get_table(table_id = "budget-local", # table ID, see `sp_tables`
                           year = 2019,
                           month = 9)
#> ℹ Building URL for dataset 'finm': FIN 2-12 M - Plnění rozpočtu MŘO, '2019-09'
#> ℹ Get the dataset documentation at 'http:/monitor.statnipokladna.cz/data/struktura/finm.xlsx'
#> ✓ Storing downloaded archive in and extracting to '/var/folders/c8/pj33jytj233g8vr0tw4b2h7m0000gn/T/Rtmp52TEmf/statnipokladna/finm/2019/09/'
#> ℹ Set dest_dir for more control over downloaded files.
#> ℹ Reading data...
#> ℹ Transforming data...

The data is automatically downloaded to a temp directory, so it will be reused by future calls to sp_get_table() made in the same session, unless you set force_redownload = TRUE. You set the dest_dir parameter e.g. to ".", a directory will be created in your current working directory and the data will be downloaded into it so that it can persist across sessions.

It is a rather raw-looking data frame…

This contains all codes for this codelist, some of which are not valid for the time period of our core data. The function add_codelist() resolves this automatically.

As you can see below, you can

add multiple codelists in one pipe
add a codelist without downloading it first - just pass its ID to the function as a character instead of an object.

Codelists are also cached, but you have one in your namespace, you can pass it as an object, provided that it has the right columns.

Background information

Note that while the package provides a bridge from complicated data dumps to a clean data structure, you still need quite a bit of domain knowledge to be able analyse the data safely.

See the “How the data works” vignette (in Czech only, the terminology is impossible to translate) for an overview of the structure of the data on which this package draws. This also contains some notes useful for interpreting the data.

A subset of this information is in the Get started vignette.

There is also a log of various data gotchas I discovered, also in Czech only, stored in the data issues vignette.

A basic glossary of some of the terms used in the data sets is at http://monitor.statnipokladna.cz/metodika/.

Note

Not created or endorsed by the Czech Ministry of Finance, who produce the data - but they definitely deserve credit for releasing the data and maintaining the application.
