rio (version 0.5.29)

rio: A Swiss-Army Knife for Data I/O


The aim of rio is to make data file input and output as easy as possible. export and import serve as a Swiss-army knife for painless data I/O for data from almost any file format by inferring the data structure from the file extension, natively reading web-based data sources, setting reasonable defaults for import and export, and relying on efficient data import and export packages. An additional convenience function, convert, provides a simple method for converting between file types.

Note that some of rio's functionality is provided by ‘Suggests’ dependendencies, meaning they are not installed by default. Use install_formats to make sure these packages are available for use.



GREA provides an RStudio add-in to import data using rio.
