fr

fr provides fr_tdr, fr_schema, and fr_field objects for implementing frictionless tabular-data-resource standards in R.

Installation

Install {fr} from CRAN:

install.packages("fr")

You can install the development version of {fr} from GitHub with:

# install.packages("pak")
pak::pak("cole-brokamp/fr")

Usage

• See vignette("read_fr_tdr") to read a Frictionless Tabular Data Resource from disk or the web, access metadata, and manipulate it as a data.frame
• See vignette("creating_a_tabular-data-resource") to create a Frictionless Tabular Data Resource by converting a data.frame or tibble, adding metadata, and writing to disk

Frictionless Standards

Developed by the Open Knowledge Foundation, the frictionless standards are a set of patterns for describing data, including datasets (Data Package), files (Data Resource), and tables (Table Schema). A Data Package is a simple container format used to describe and package a collection of data and metadata, including schemas. These metadata are contained in a specific file (separate from the data file), usually written in JSON or YAML, that describes something specific to each Frictionless Standard:

• Table Schema: describes a tabular file by providing its dimension, field data types, relations, and constraints
• Data Resource: describes an exact tabular file providing a path to the file and details like title, description, and others
• Tabular Data Resource = Data Resource + Table Schema
• CSV dialect: describes the formatting specific to the various dialects of CSV files
• Data Package & Tabular Data Package: describes a collection of tabular files providing data resource information from above along with general information about the package itself, a license, authors, and other metadata

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.
