rio 1.1.1
Bug fixes
- Fix #425 for archive formats, the file extension of the input file
is determined by the compressed file (like prior rio 1.1.0)
rio 1.1.0
rio 1.0.3
- Add trustparameter to functions that are used to load
various R environment formats (.R,.Rds,.Rdata, etc). This parameter is defaulted toTRUEtoday to ensure backwards compatibility. A deprecation
notice warns this will default toFALSEinrio2.0. We are informing users that these data types should only be loaded
from trusted sources, which should be affirmatively attested to.
- Test and fix the compression mechanism: Gzip, Bzip2 are now working
as expected.
Bug fixes
- Fix #412, prevent double usage of whichfor archive
formats
- Fix #415, both import_list()andexport_list()support tar archives.
- Fix #421, tar export is only supported by R >= 4.0.3.
rio 1.0.2
- For missing files in import_listit gives more
informative warnings fix #389
- Single-item list of data frames can be exported fix #385
- Move stringito Suggests to reduce compilation time.
Add an attribution to the internal data to list out all required
packages #378
- Move readrto Imports forfwf.readris a dependency ofhavenso it does not
increase the number of dependencies. Remove the originalread.fwf2which doesn’t guesswidths. Keep thewidthsandcol.namesto maintain
compatibility. #381
- Add (back) a pkgdown website: https://gesistsa.github.io/rio/
- Update all test cases #380
rio 1.0.1
- POTENTIALLY BREAKING: Due to compiling time concerns, roll back the
decision to move arrowtoImports. It is nowSuggests.setclass = "arrow"works ifarrowis installed. #315 #376
rio 1.0.0
- Stop loading the entire namespace of a suggested package when it is
available #296
- Unexport objects: .import,.export,is_file_text; remove documentation forarg_reconcile#321
- Update Examples to make them more realistic #327
- Add support for qs#275 h/t David Schoch
- Use arrowto import / exportfeather#340
- export_listcan write multiple data frames to a single
archive file (e.g. zip, tar) or a directory #346 h/t David Schoch
- get_infois added #350
- POTENTIALLY BREAKING: setclassparameter is now
authoritative. Therefore:import("starwars.csv", data.table = TRUE, setclass = "tibble")will return a tibble (unlike previous versions where a data.table is
returned). The default class is data frame. You can either explicitly
use thesetclassparameter; or set the option:options(rio.import.class = "data.table"). h/t David Schoch
#336
- Parquet and feather are now formats supported out of the box;
Possible to setclass to arrow/arrow_table;
ArrowTabular class can be exported #315
- Add “extension”, “labelled” vignettes
- Support readODS 2.1.0 features such as reading and writing Flat ODS;
export Multiple data frames #358
- POTENTIALLY BREAKING: Use writexlinstead ofopenxlsx. Option to read xlsx withopenxlsx(i.e.import("starwars.xlsx", readxl = FALSE)) is alwaysTRUE. The ability to overwrite an existing sheet in an
existing xlsx file is also removed. It is against the design principle
ofrio.
- POTENTIALLY BREAKING: The following options are deprecated:
import(fread),import(readr = TRUE),import(haven),import(readxl)andexport(fwrite). import will almost usedata.table,haven,readxl, and
internal function (for fwf) to import and export data. Currently, those
options stay for backward compatibility but will be removed in v2.0.0.
#343 h/t David Schoch
- POTENTIALLY BREAKING: ...is handled differently.
Underlying functions using “Tidy” convention
(e.g.readxl::read_xlsx()) can use “Base Convention” (See
the new vignette:remap). Unused arguments passed to the
underlying function as...are silently ignored by default.
A new optionrio.ignoreunusedargsis added to control this
behavior. #326
- Bug fixes
- … is correctly passed for exporting ODS and feather #318
- POTENTIALLY BREAKING: JSON are exported in UTF-8 by default; solved
encoding issues on Windows R < 4.2. This won’t affect any modern R
installation where UTF-8 is the default. #318
- POTENTIALLY BREAKING: YAML are exported using yaml::write_yaml().
But it can’t pass the UTF-8 check on older systems. Disclaimer added.
#318
- More check for the fileargument #301
- import_listworks with single Excel/HTML/Zip online
#294
- Correct XML/HTML escaping #303
- Create directory if it doesn’t exist #347
 
- Declutter
- remove the obsolete data.table option #323
- write all documentation blocks in markdown #311
- remove all @importFrom #325 h/t David Schoch
- rearrange “Package Philosophy” as a Vignette #320
- Create a single source of truth about all import and export
functions #313
- Clarify all concepts: now there is only format#351

specified sheet (if it exists) is overwritten. If the file exists but
thewhichsheet does not, the data are added as a new sheet
to the existing workbook. (#156)
rio 0.5.7
- Import of files with the ambiguous .dat extension, which are
typically text-delimited files, are now passed to
data.table::fread()with a message. Export to the format

that were failing on certain CRAN builds.
rio 0.5.4
- New functions characterize()andfactorize()provide methods for converting “labelled”
variables (e.g., from Stata or SPSS) into character or factor variables

respectively, thus (finally) providing Linux support. (#105, h/t Matthew
Lincoln)
- Added an rbindargument toimport_list().
(#149)
- Added a setclassargument toimport_list(), ala the same inimport().

rio 0.3.17
- Fixed a bug in import from remote URLs with incorrect file
extensions.
rio 0.3.16
- Added support for import from fixed-width format files via
readr::read_fwf()with a specifiedwidthsargument. This may enable faster import of these types of files and
provides a base-like interface for working with readr. (#48)
rio 0.3.15
- Added support for import from and export to yaml. (#83)
- Fixed a bug when reading from an uncommented CSVY yaml header that

S3 generics and documentation has been added to describe how to write
rio extensions for new file types. An example of this functionality is
shown in the new suggested “rio.db” package.
rio 0.3.11
- import()now uses xml2 to read XML structures and- export()uses a custom method for writing to XML, thereby
negating dependency on the XML package. (#67)
- Enhancements were made to import and export of CSVY to store
attribute metadata as variable-level attributes (like imports from
binary file formats).
- import()gains a- whichargument that is
used to select which file to return from within a compressed tar or zip
archive.
- Export to tar now tries to correct for bugs in tar()that are being fixed in base R via PR#16716.
rio 0.3.10
- Fixed a bug in import()(introduced in #62, 7a7480e5)
that prevented import from clipboard. (h/t Kevin Wright)
- export()returns a character string. (#82)
rio 0.3.9
- The use of import()for SAS, Stata, and SPSS files has
been streamlined. Regardless of whether thehaven = TRUEargument is used, the data.frame returned byimport()should now be (nearly) identical, with all attributes stored at the
variable rather than data.frame level. This is a non-backwards
compatible change. (#80)
rio 0.3.8
- Fixed error in export to CSVY with a commented yaml header. (#81,
h/t Andrew MacDonald)
rio 0.3.7
- export()now allows automatic file compression as tar,
gzip, or zip using the- fileargument (e.g.,- export(iris, "iris.csv.zip")).
rio 0.3.6
- Expanded verbosity of export()for fixed-width format
files and added a commented header containing column class and width
information.
- Exporting factors to fixed-width format now saves those values as
integer rather than numeric.
- Expanded test suite and separated tests into format-specific files.
(#51)
rio 0.3.5
- Export of CSVY files now includes commenting the yaml header by
default. Import of CSVY accommodates this automatically. (#74)
rio 0.3.3
- Export of CSVY files and metadata now supported by
export(). (#73)
- Import of CSVY files now stores dataset-level metadata in attributes
of the output data.frame. (#73, h/t Tom Aldenberg)
- When rio receives an unrecognized file format, it now issues a
message. The new internal .import.default()and.export.default()then produce an error. This enables
add-on packages to support additional formats through new s3 methods of
the form.import.rio_EXTENSION()and.export.rio_EXTENSION().
rio 0.3.2
- Use S3 dispatch internally to call new (unexported)
.import()and.export()methods. (#42, h/t
Jason Becker)
rio 0.3.0
- Release to CRAN.

rio 0.2.6
- Cleaned up NAMESPACE file.
rio 0.2.5
- If file format for a remote file cannot be identified from the
supplied URL or the final URL reported by
curl::curl_fetch_memory(), the HTTP headers are checked for
a filename in the Content-Disposition header. (#36)
- Removed longurl dependency. This is no longer needed because we can
identify formats using curl’s url argument.
- Fixed a bug related to importing European-style (“csv2”) format
files. (#44)
- Updated CSVY import to embed variable-level metadata. (#52)
- Use urltools::url_parse()to extract file extensions
from complex URLs (e.g., those with query arguments). (#56)
- Fixed NAMESPACE notes for base packages. (#58)
rio 0.2.4
- Modified behavior so that files imported using haven now store
variable metadata at the data.frame level by default (unlike the default
behavior in haven, which can cause problems). (#37, h/t Ista Zahn)
- Added support for importing CSVY (http://csvy.org/) formatted files.
(#52)
- Added import dependency on data.table 1.9.5. (#39)
rio 0.2.2
- Uses the longurl package to expand shortened URLs so that their file
type can be easily determined.
rio 0.2.1
- Improved support for importing from compressed directories,
especially web-based compressed directories. (#38)
- Add import dependency on curl >= 0.6 to facilitate content type
parsing and format inference from URL redirects. (#36)

files.
- Expanded the set of supported file types/extensions, switched SPSS,
SAS, and Stata formats to haven, making its use
optional.
