git2rdata 0.5.2

CRAN release: 2026-04-08

• write_vc() gains an optional convert argument for specifying column conversions. Conversions are applied before storing and reversed when reading data back. The convert information is stored in the metadata and added to the data frame attributes.
• read_vc() now applies conversions specified in the metadata and adds the convert information to the data frame attributes.
• Bugfix in rename_variable() thanks to @florisvdh for finding and fixing the bug.

git2rdata 0.5.1

CRAN release: 2025-12-10

• write_vc() stores metadata stored in the data frame.
• read_vc() returns more metadata.
• read_vc() can handle empty factors.
• recent_commit() now returns handles multiple commits within the same second.

git2rdata 0.5.0

CRAN release: 2025-01-24

• read_vc() handles empty datasets stored with split_by.
• write_vc() and meta() gain a digits argument. The arguments specifies the number of significant digits to store for numeric values.

git2rdata 0.4.1

CRAN release: 2024-09-06

• Add update_metadata() to update the description of a git2rdata object. See vignette("metadata") for more details.
• Update the checklist and pkgdown infrastructure.

git2rdata 0.4.0

CRAN release: 2022-03-17

New features

• write_vc() stores non optimised files as comma separated values rather than tab separated values. The general public seems to better recognised .csv files than .tsv files as being data files.
• Add a new function verify_vc() which reads a git2rdata object and verifies the presence of a set of variables. It return the data upon success.

Internal changes

• Upgrade to Roxygen2 7.1.2
• Add inst/CITATION, CITATION.cff, .zenodo.json

git2rdata 0.3.1

CRAN release: 2021-01-21

• Use icuSetCollate() to define a standardised sorting.

git2rdata 0.3.0

New features

• write_vc() gains an optional split_by argument. See vignette("split_by") for more details.
• rename_variable() efficiently renames variables in a stored git2rdata object.

Bugfixes

• read_vc(), is_git2rdata() and is_git2rmeta() now yield a better message when both the data and metadata are missing.

git2rdata 0.2.2

• Use the checklist package for CI.

git2rdata 0.2.1

CRAN release: 2020-03-02

Bugfixes

• Explicitly use the stringsAsFactors of data.frame() in the examples and unit tests if the dataframe contains characters. The upcoming change in default value of stringsAsFactors requires this change. See https://developer.r-project.org/Blog/public/2020/02/16/stringsasfactors/index.html

git2rdata 0.2.0

CRAN release: 2019-11-18

BREAKING FEATURES

• Calculation of data hash has changed (#53). You must use upgrade_data() to read data stored by an older version.
• is_git2rdata() and upgrade_data() no longer not test equality in data hashes (but read_vc() still does).
• write_vc() and read_vc() fail when file is a location outside of root (#50).
• Reordering factor levels requires strict = TRUE.

Bugfixes

• Linux and Windows machines now generated the same data hash (#49).

NEW FEATURES

• Internal sorting uses the “C” locale, regardless of the current locale.
• read_vc() reads older stored in an older version (#44). When the version is too old, it prompts to upgrade_data().
• Improve warnings() and error() messages.
• Use vector version of logo.

git2rdata 0.1

CRAN release: 2019-06-17

• Transfer to rOpenSci.
• Use new logo (@peterdesmet, #37).
• Add estimate of upper bound of the number of commits.

git2rdata 0.0.5

• upgrade_data() uses the same order of the metadata as write_vc().

git2rdata 0.0.4

BREAKING FEATURES

• write_vc() stores the git2rdata version number to the metadata. Use upgrade_data() to update existing data.

NEW FEATURES

• read_vc() checks the meta data hash. A mismatch results in an error.
• The meta data gains a data hash. A mismatch throws a warning when reading the object. This tolerates updating the data by other software, while informing the user that such change occurred.
• is_git2rmeta() validates metadata.
• list_data() lists files with valid metadata.
• rm_data() and prune_meta() remove files with valid metadata. They don’t touch tsv file without metadata or yml files not associated with git2rdata.
• Files with invalid metadata yield a warning with list_data(), rm_data() and prune_meta().

Bugfixes

• write_vc() and relabel() handle empty strings ('') in characters and factors (#24).
• read_vc() no longer treats # as a comment character.
• read_vc() handles non ASCII characters on Windows.

Other changes

• Use a faster algorithm to detect duplicates (suggestion by @brodieG).
• Improve documentation.
• Fix typo’s in documentation, vignettes and README.
• Add a rOpenSci review badge to the README.
• The README mentions on upper bound on the size of dataframes.
• Set lifecycle to “maturing” and repo status to “active”.
• The functions handle root containing regex expressions.
• Rework vignette("workflow", package = "git2rdata").
• Update timings in vignette("efficiency", package = "git2rdata")
• Minor tweaks in vignette("plain_text", package = "git2rdata")

git2rdata 0.0.3

• Fix typo’s in documentation, vignettes and README.

git2rdata 0.0.2

BREAKING CHANGES

• meta() appends the metadata as a list to the objects rather than in YAML format.
• yaml::write_yaml() writes the metadata list in YAML format.
• write_vc() now uses the ‘strict’ argument instead of ‘override’.
• rm_data() removes the data files. Use prune_meta() to remove left-over metadata files (#9).

NEW FEATURES

• Vignette on efficiency added (#2).
• Three separate vignettes instead of one large vignette.
  • Focus on the plain text format.
  • Focus on version control.
  • Focus on workflows.
• S3 methods replace the old S4 methods (#8).
• Optimized factors use stable indices. Adding or removing levels result in smaller diffs (#13).
• Use relabel() to alter factor levels without changing their index (#13).
• write.table() stores the raw data instead of readr::write_tsv() (#7). This avoids the readr dependency.
• write_vc() and read_vc() use the current working directory as default root (#6, @florisvdh).
• The user can specify a string to code missing values (default = NA). This allows the storage of the character string "NA".
• write_vc() returns a list of issues which potentially result in large diffs.
• list_data() returns a vector with dataframes in the repository.

Other changes

• write_vc() allows to use a custom NA string.
• Each helpfile contains a working example (#11).
• README updated (#12).
  • Updated the rationale with links to the vignettes.
  • git2rdata has a hexagon sticker logo.
  • Add the .
  • The installation instructions use remotes and build the vignettes.
• We removed auto_commit() because of limited extra functionality over git2r::commit().

git2rdata 0.0.1

NEW FEATURES

• Use readr to write and read plain text files.
• Allow storage of strings with “NA” or special characters.
• Handle ordered factors.
• Stop handling complex numbers.
