Overview

About

Maintained by Jennifer BryanCRAN page ↗GitHub ↗Website ↗Issues ↗Declared funder: Posit Software, PBC

The goal of 'readr' is to provide a fast and friendly way to read rectangular data (like 'csv', 'tsv', and 'fwf'). It is designed to flexibly parse many types of data found in the wild, while still cleanly failing when data unexpectedly changes.

Changes in 2.2.0

This release advances many deprecations.

melt_csv(), melt_csv2(), melt_delim(), melt_tsv(), melt_fwf(), melt_table(), melt_table2(), and all melt_*_chunked() variants have been removed from readr. These functions were deprecated in readr 2.0.0 (2021-07-20). See the meltr package (https://github.com/r-lib/meltr).
read_table2() has been removed from readr. This function was deprecated in readr 2.0.0 (2021-07-20) in favor of read_table(). Use read_table() instead.
read_csv(), read_csv2(), read_tsv(), read_delim(), and read_fwf() now emit a deprecation warning when literal data is passed without wrapping it in I(). For example, usage like read_csv(I("x,y\n1,2")) is preferred over read_csv("x,y\n1,2") (#1611).
The quote_escape parameter has been removed from write_delim(), write_csv(), write_csv2(), write_excel_csv(), write_excel_csv2(), write_tsv(), format_delim(), format_csv(), format_csv2(), and format_tsv(). This parameter was deprecated in readr 2.0.0 (2021-07-20) in favor of the escape parameter. Use escape instead.
The path parameter has been removed from write_delim(), write_csv(), write_csv2(), write_excel_csv(), write_excel_csv2(), write_tsv(), write_lines(), write_file(), and write_rds(). This parameter was deprecated in readr 1.4.0 (2020-01-31) in favor of the file parameter. Use file instead.
The skip_empty_rows argument of fwf_empty() now throws an error if used in edition 2. This argument was deprecated in readr 2.0.0 (2021-07-20).
The quoted_na argument now throws an error if used in edition 2 with read_delim(), read_csv(), read_csv2(), or read_tsv(). This usage was first deprecated in readr 2.0.0 (2021-07-20).

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("readr", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("tidyverse/readr")

Development version from tidyverse/readr. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-readr

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-readr

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-readr

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
