Description Usage Arguments Details Value Note Author(s) References See Also

A function (in development!) that writes a file to be processed by LilyPond by extracting the relevant information (e.g. pitch, length, ...) from columns of a data frame. The music notation software LilyPond can “transcribe” such an input file into sheet music.

lilyinput(X, file = "Rsong.ly", Major = TRUE, key = "c", 
    clef = c("treble", "bass", "alto", "tenor"), time = "4/4", 
    endbar = TRUE, midi = TRUE, tempo = "2 = 60", 
    textheight = 220, linewidth = 150, indent = 0, fontsize = 14)

`X`	A data frame containing 4 named components (columns): `note`: Integer - the notes' pitch in halftones from diapason (a), i.e. 0 for diapason a, 3 for c', ... `length`: Integer - denominator of lengths of the notes, e.g. 8 for a quaver. `punctate`: Logical - whether to punctate a note. `slur`: Logical - `TRUE` indicates to start a slur, or to end it. That means that the first, third, ... occurences of `TRUE` start slurps, while the second, fourth, ... occurences end slurps. Note that it is only possible to draw one slur at a time.
`file`	The file to be written for LilyPond's input.
`Major`	Logical indicating major key (if `TRUE`) or minor key.
`key`	Keynote, necessary to set sharps/flats.
`clef`	Integer indicating the kind of clef, supported are `"treble"` (default), `"bass"`, `"alto"`, and `"tenor"`.
`time`	Character indicating which meter to use, examples are: `"3/4"`, `"4/4"`.
`endbar`	Logical indicating whether to set an ending bar at the end of the sheet music.
`midi`	Logical indicating whether Midi output (by LilyPond) is desirable.
`tempo`	Character specifying the tempo to be used for the Midi file if `midi = TRUE`. The default, `"2 = 60"` indicates: 60 half notes per minute, whereas `"4 = 90"` indicates 90 quarters per minute.
`textheight`	Textheight of the sheet music to be written by LilyPond.
`linewidth`	Linewidth of the sheet music to be written by LilyPond.
`indent`	Indentation of the sheet music to be written by LilyPond.
`fontsize`	Fontsize of the sheet music to be written by LilyPond.

Details will be given when development has reached a stable stage ...!

Nothing is returned, but a file is written.

This function is in development!!!
Everything (and in particular its user interface) is subject to change!!!

quantMerge prepares the data to be written into the LilyPond format; quantize and quantplot generate another kind of plot; and exhaustive example is given in tuneR.
