readODS

CRAN status Lifecycle: stable Codecov test coverage R-CMD-check

The only goal of readODS is to enable R to read and write OpenDocument Spreadsheet (ODS) files.

Installation

Install the latest stable version from CRAN:

install.packages("readODS")

Or install the development version from Github:

devtools::install_github("chainsawriot/readODS")

Usage

In almost all use cases, you only need two functions: read_ods and write_ods. Simple.

Reading

library(readODS)
read_ods("starwars.ods")
#>                  Name homeworld species
#> 1      Luke Skywalker  Tatooine   Human
#> 2               C-3PO  Tatooine   Human
#> 3               R2-D2  Alderaan   Human
#> 4         Darth Vader  Tatooine   Human
#> 5         Leia Organa  Tatooine   Human
#> 6           Owen Lars  Tatooine   Human
#> 7  Beru Whitesun lars   Stewjon   Human
#> 8               R5-D4  Tatooine   Human
#> 9   Biggs Darklighter  Kashyyyk Wookiee
#> 10     Obi-Wan Kenobi  Corellia   Human

About the speed and file size

This package is written entirely in R. Although the efficiency has been improved, please don’t expect the heavily optimized performance of readxl, readr and data.table’s fread.

Also, this package can’t handle ODS files larger than “medium size”. See issue #71.

If you need to read and write large ODS files efficiently, the headless interface of LibreOffice is recommended. See issue #49 for an example.

The creator of this package is Gerrit-Jan Schutten. The current maintainer is Chung-hong Chan. This package benefits from contributions by Thomas J. Leeper, John Foster, Sergio Oller, Jim Hester, Stephen Watts, Arthur Katossky, Stas Malavin, Duncan Garmonsway, and Mehrad Mahmoudian.

This package emulates the behaviors of readxl::read_xlsx, writexl::write_xlsx and xlsx::write.xlsx.

This package should be a silent member of rio, so that you don’t need to care about file format anymore.
