tabr 0.3.0 release

• Added fretboard_plot for making fretboard diagrams outside of the LilyPond tablature pipeline. This necessitates importing ggplot2.
• Added functions for phrase validation, coercion and decomposition back to original character string inputs.
• Added functions for note, pitch, chord and octave equivalence checks.
• Added a collection of functions for constructing and working with common chords. The chord constructors are among the chord_*-named functions and also have shorter x*-named aliases. These are "piano chords," i.e., based on the condensed, defining intervals.
• Added guitarChords dataset containing several thousand formations of guitar chord voicings.
• Added helper functions that use guitarChords for obtaining guitar chord information and mapping between different defining properties of a chord, most notably the addition of gc_notes and gc_fretboard for mapping chord names to noteworthy strings and fretboard diagram syntax.
• Added helper functions for working with basic note/pitch strings.
• Added helper functions for working with musical scales and modes.
• Added helper functions for working with musical intervals.
• Added noteworthy class, used internally, optional for users (includes custom print and summary methods).
• Added mainIntervals dataset.
• Added more internal checks of note and chord syntax validity across functions that work with string representations (pre-phrase object construction).
• Update older functions to utilize the new, more robust and stricter validation checks and offer more consistent noteworthy class output.
• updated transpose to handle additional edge cases, including a new style option, strip.
• Updated and added new unit tests.
• Bug fix for case where NA-valued no-chord rests (s or r) were unnamed in output of chord_set.
• Fixed entry in tabrSyntax.
• Fix class assignment bug and updated as_phrase.
• Added a new column of relative interval size to internal .keydata helper table.
• Added new vignettes focusing on the programming aspect of tabr.
• Updated documentation.

tabr 0.2.0 release

• Refactored tuplet (and triplet) to accept a phrase object as well as a character string of notes. Previously, only notes were accepted but this was too limiting. The argument name has changed to from notes to x and tuplet will now check the class of x and handle phrase objects accordingly.
• Added handling of silent rests in note strings for tuplet.
• sf_phrase (and sfp) updated to allow returning early with only the notes string as opposed to the entire phrase object. This is useful if you just want a quick, cleaner string representation of what notes are mapped by string/fret combinations.
• Minor updates to .onLoad for non-Windows systems.
• Removed tibble package dependency. Using only dplyr suffices.
• Updated Readme and basic example intro vignette.
• Added and updated unit tests.
• Added lintr to Suggests field in DESCRIPTION per CRAN maintainer request regarding testthat unit tests.

tabr 0.1.2 release

tabr 0.1.2

• Unwrapped lilypond example from dontrun tag.
• Switched to tempdir() location for examples that write files.
• Added LilyPond to SystemRequirements field in DESCRIPTION.
• Attempt to run file-writing examples and file-writing unit tests conditionally if LilyPond found on system.

tabr 0.1.1

Adjustments to meet requirements for CRAN resubmission:

• Updated DESCRIPTION.
• Adjusted file-writing locations for unit tests to use tempdir.
• Add dontrun tag around one last file-writing package example that was using lilypond.
• Update lilypond, tab, midily and miditab to work with system calls that use absolute paths for output files instead of only working with relative paths.

tabr 0.1.0

• Added package scaffolding.
• Developed initial functions for music description and organization.
• Developed initial functions for generating Lilypond (.ly) files and wrapping around system calls to Lilypond for rendering sheet music to pdf or png.
• Added readme with basic example.
• Added initial vignette content.
• Added unit tests.
• Added support for custom, non-standard guitar tunings and instruments with different numbers of strings, up to seven.
• Added .mid to .ly and .mid to tab output convenience functions.
• Added support for multiple voices per staff.
• Added support for transposition of music staff relative to tablature staff.
