corporaexplorer 0.9.0.9000

corporaexplorer 0.9.0 (2024-09-02)

Breaking changes

New arguments (and new order of arguments) in prepare_data():

• text_column: Any character column can be specified as as the column containing the main textual data (not only 'Text' as before). Thanks to @discoleo for suggestion (#31).

Changes in reserved column names (see ?prepare_data for details). In particular, Year is now allowed.

Other changes

• Non-date-based corpora can now contain column called 'Date'.
• Introduced nicer display of searches with (exactly) two search terms (feebc552, feebc552e4, 325aeb3b).

Future removal

Added warning that the 'run_document_extractor()' app will be removed in a future version of corporaexplorer.

Bug fix:

Fixed filtering by dates (8c1a175b)

Other

• Changed internals to avoid ggplot2 warning
• Changing testing library to shinytest2
• Change in testing due to changes in data.table (thanks for heads-up, @MichaelChirico)

corporaexplorer 0.8.5 (2022-04-08)

• re2 regex engine again included, now using the 're2' package. This significantly speeds up many search operations. Thank you, @girishji! See https://github.com/girishji/re2
• Small UI fixes

• Changed the way colours are represented in document visualisation (63b3857)

corporaexplorer 0.8.2 (2020-03-07)

re2r regex engine disabled

Other

corporaexplorer 0.8.1.1 (2020-02-07)

New arguments

• Added columns_for_ui_checkboxes argument to prepare_data() in order to include sidebar checkboxes for convenient filtering by categorical variable/column (not necessarily factor type, but most helpful when limited number of values in the variable) in the explorer app (explore()).

Other

• Removed dependencies on packages forcats, shinycssloaders, and zoo.
• Fixed reactive issue leading to plots rendering twice when size was different from previous plot (now one has to click button to update plot size).
• Other minor bug fixes.
• Internal changes related to extension packages.

corporaexplorer 0.8.0 (2019-12-02)

Breaking API changes

• run_corpus_explorer() is deprecated and replaced with explore().
  • explore() works in the precise same way as run_corpus_explorer(), but is faster to type and makes a nice pair with the new explore0() function (see below).
  • run_corpus_explorer() still works (as a thin wrapper to explore()), but yields a warning.
• Removed normalise argument from prepare_data()
• Added within_group_identifier and tile_length_range arguments in prepare_data() (leading to new order of arguments)

New function

• Added explore0(), a convenience function to directly explore a data frame or character vector without first creating a 'corporaexplorerobject' with prepare_data().

Demo apps

• Included demo apps: Jane Austen's novels and State of the Union addresses, with data from the janeaustenr and sotu packages, respectively. See run_janeausten_app() and run_sotu_app()

Other

• Minimum corpus plot height is again 100.

corporaexplorer 0.7.0 (2019-11-15)

Breaking API changes

• Added search_options argument to run_corpus_explorer(), and moved the arguments use_matrix, regex_engine, optional_info, allow_unreasonable_patterns there.
• Added plot_options argument (with several possibilities to customise plot colours etc.) to run_corpus_explorer(), and moved the max_docs_in_wall_view setting there.

Other

• Greatly simplified deployment to Shiny Server and shinyapps.io etc. (#19). See article on the package website.
• Improved app experience on small screens (avoiding cluttering of ui elements).
• Updated LICENSE file with license for jQuery.scrollTo.
• Plot minimum height set to 50.
• Minor app CSS twitches.

API changes
