• Fix bug introduced when re2 was reintroduced (4eeb2f3), which caused app to crash when searching in custom columns/metadata

• 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

• Fixed bug where time selection slider widget in calendar view did not work (#25)

• Fixed bugs and warning messages caused by changes in other packages (tibble and dplyr).
• Fixed special case of warnings occurring when visualising documents with zero hits (2270046)
• Changed the way colours are represented in document visualisation (63b3857)

re2r regex engine disabled

• Because ‘re2r’ will be removed/archived by the CRAN maintainers. See https://github.com/qinwf/re2r/issues/22.

Other

• The apps now allow any mix of whitespace in input terms

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.

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.

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.

corporaexplorer 0.6.3

API changes

• Add ui_options argument to run_corpus_explorer().
• Add search_input argument to run_corpus_explorer().

Bug fixes

• Print method for corporaexplorerobject now works properly
• Open but empty "Filter corpus" field no longer disables time filtering

Other

• Documentation moved to https://kgjerde.github.io/corporaexplorer

Only minor internal changes to satisfy specific CRAN criteria.
