string_unfold

string_fold

Fold or unfold a string on the expansion operator.

Provides a music notation syntax and a collection of music
programming functions for generating, manipulating, organizing, and analyzing
musical information in R. Music syntax can be entered directly in character
strings, for example to quickly transcribe short pieces of music. The
package contains functions for directly performing various mathematical,
logical and organizational operations and musical transformations on special
object classes that facilitate working with music data and notation. The
same music data can be organized in tidy data frames for a familiar and
powerful approach to the analysis of large amounts of structured music data.
Functions are available for mapping seamlessly between these formats and
their representations of musical information. The package also provides an
API to 'LilyPond' (<https://lilypond.org/>) for transcribing musical
representations in R into tablature ("tabs") and sheet music. 'LilyPond' is
open source music engraving software for generating high quality sheet music
based on markup syntax. The package generates 'LilyPond' files from R code
and can pass them to the 'LilyPond' command line interface to be rendered
into sheet music PDF files or inserted into R markdown documents. The
package offers nominal MIDI file output support in conjunction with
rendering sheet music. The package can read MIDI files and attempts to
structure the MIDI data to integrate as best as possible with the data
structures and functionality found throughout the package.
