Manipulate DESCRIPTION Files

Tools to read, write, create, and manipulate DESCRIPTION files. It is intended for packages that create or manipulate other packages.

Interface to Unidata netCDF (Version 4 or Earlier) Format Data Files

Provides a high-level R interface to data files written using Unidata's netCDF library (version 4 or earlier), which are binary data files that are portable across platforms and include metadata information in addition to the data sets. Using this package, netCDF files (either version 4 or "classic" version 3) can be opened and data sets read in easily. It is also easy to create new netCDF dimensions, variables, and files, in either version 3 or 4 format, and manipulate existing netCDF files. This package replaces the former ncdf package, which only worked with netcdf version 3 files. For various reasons the names of the functions have had to be changed from the names in the ncdf package. The old ncdf package is still available at the URL given below, if you need to have backward compatibility. It should be possible to have both the ncdf and ncdf4 packages installed simultaneously without a problem. However, the ncdf package does not provide an interface for netcdf version 4 files.

Analysis of Oceanographic Argo Floats

Supports the analysis of oceanographic data recorded by Argo autonomous drifting profiling floats. Functions are provided to (a) download and cache data files, (b) subset data in various ways, (c) handle quality-control flags and (d) plot the results according to oceanographic conventions. A shiny app is provided for easy exploration of datasets. The package is designed to work well with the 'oce' package, providing a wide range of processing capabilities that are particular to oceanographic analysis. See Kelley, Harbin, and Richards (2021) for more on the scientific context and applications.

Using 'Mathjax' in Rd Files

Provides 'MathJax' and macros to enable its use within Rd files for rendering equations in the HTML help files.

Download and Tidy 'HMRC' Statistical Data

Provides functions to download, parse, and tidy statistical data published by 'HM Revenue and Customs' ('HMRC') on 'GOV.UK'. Returns annotated 'hmrc_tbl' data frames with provenance metadata (source URL, fetch time, vintage, cell methods) for reproducible fiscal research. Covers monthly tax receipts (41 tax heads from 2008), 'VAT' (from 1973), fuel duties (from 1990), tobacco duties (from 1991), annual 'Corporation Tax' receipts, stamp duty, research and development tax credit statistics (from 2000), tax gap estimates, 'Income Tax' liabilities by income range, and monthly property transaction counts. File URLs are resolved at runtime via the 'GOV.UK' Content API < https://www.gov.uk/api/content>, so data is always current without hardcoded URLs. Files are cached locally between sessions.

Retrieve Time Series Data from 'Banco de España'

Tools for retrieving 'Banco de España' ('BdE') time series data as 'tibble' objects from bulk CSV files and the 'Statistics web service (API)'. Bulk CSV functions use stable 'BdE' sequential numbers, while API functions use API series codes. Catalog functions support discovery and local caching. Plotting helpers provide 'ggplot2' palettes, scales and themes. 'Banco de España' is the national central bank and, within the framework of the Single Supervisory Mechanism ('SSM'), the supervisor of the Spanish banking system alongside the European Central Bank. This package is not sponsored, endorsed or administered by 'Banco de España'.

Split, Combine and Compress PDF Files

Content-preserving transformations transformations of PDF files such as split, combine, and compress. This package interfaces directly to the 'qpdf' C++ library < https://qpdf.sourceforge.io/> and does not require any command line utilities. Note that 'qpdf' does not read actual content from PDF files: to extract text and data you need the 'pdftools' package.

In-Line Documentation for R

Generate your Rd documentation, 'NAMESPACE' file, and collation field using specially formatted comments. Writing documentation in-line with code makes it easier to keep your documentation up-to-date as your requirements change. 'roxygen2' is inspired by the 'Doxygen' system for C++.

Access Tidy Education Finance Data

Provides easy access to tidy education finance data using Bellwether's methodology to combine NCES F-33 Survey, Census Bureau Small Area Income Poverty Estimates (SAIPE), community data from the ACS 5-Year Estimates, the Comparable Wage Index for Teachers (CWIFT) from NCES EDGE, and school district land area from U.S. Census Bureau Gazetteer Files. The package simplifies downloading, caching, and filtering education finance data by year and state, enabling researchers and analysts to explore K-12 education funding patterns, revenue sources, expenditure categories, and demographic factors across U.S. school districts.

Access and Analysis of Bolivian Census Microdata

Programmatic access to the microdata of the Bolivian population and housing censuses of 1976, 1992, 2001, 2012 and 2024, published by the National Statistics Institute of Bolivia (INE, < https://www.ine.gob.bo/>). Data files in Apache Parquet format are downloaded on demand from a companion data repository, cached locally, and can be filtered by department, province or municipality. Supports 'dplyr' workflows through Apache Arrow and SQL queries through 'DuckDB'. Includes variable dictionaries for every census year with a thematic taxonomy and contextual metadata (reference population, questionnaire item number and provenance of each variable), derived from the census questionnaires and from the Data Documentation Initiative (DDI) files of the INE ANDA catalogue; functions to harmonise variables across censuses for temporal comparison; and choropleth maps at the department and municipality level. Also includes the 2024 census aggregates for urban blocks and rural communities, with their geometries. Documentation and messages are in Spanish, the language of the source data.
