Plot sheet music snippet with LilyPond

Description

These functions are wrappers around the ⁠render_music*⁠ functions. They abstract the process of rendering a sheet music snippet to png and loading the rendered image back into R to be displayed as a plot in an open graphics device or inserted into an R Markdown code chunk.

Usage

plot_music(
  music,
  clef = "treble",
  tab = FALSE,
  tuning = "standard",
  string_names = NULL,
  header = NULL,
  paper = NULL,
  colors = NULL,
  transparent = FALSE,
  res = 300
)

plot_music_tc(
  music,
  header = NULL,
  paper = NULL,
  colors = NULL,
  transparent = FALSE,
  res = 300
)

plot_music_bc(
  music,
  header = NULL,
  paper = NULL,
  colors = NULL,
  transparent = FALSE,
  res = 300
)

plot_music_tab(
  music,
  clef = NA,
  tuning = "standard",
  string_names = NULL,
  header = NULL,
  paper = NULL,
  colors = NULL,
  transparent = FALSE,
  res = 300
)

plot_music_guitar(
  music,
  tuning = "standard",
  string_names = NULL,
  header = NULL,
  paper = NULL,
  colors = NULL,
  transparent = FALSE,
  res = 300
)

plot_music_bass(
  music,
  tuning = "bass",
  string_names = FALSE,
  header = NULL,
  paper = NULL,
  colors = NULL,
  transparent = FALSE,
  res = 300
)

Arguments

music	a music object.
clef	character, include a music staff with the given clef. NA to suppress. See track() for details.
tab	logical, include tablature staff. NA to suppress. See track().
tuning	character, string tuning, only applies to tablature. See track().
string_names	label strings at beginning of tab staff. NULL (default) for non-standard tunings only, TRUE or FALSE for force on or off completely.
header	a named list of arguments passed to the header of the LilyPond file. See lilypond() details.
paper	a named list of arguments for the LilyPond file page layout. See lilypond() details.
colors	a named list of LilyPond element color global overrides. See lilypond() for details.
transparent	logical, transparent background for intermediate png file.
res	numeric, resolution, png only. Defaults to 300.

Details

While these functions abstract away the details of the process, this is not the same as making the plot completely in R. R is only displaying the intermediary png file. LilyPond is required to engrave the sheet music.

For R Markdown you can alternatively render the png using the corresponding ⁠render_music*⁠ function and then place it in the document explicitly using knitr::include_graphics(). See render_music() for more details.

Value

a plot

Examples

x <- "a,4;5*5 b,4- c4 cgc'e'~4 cgc'e'1 e'4;2 c';3 g;4 c;5 ce'1;51"
x <- as_music(x)

y <- "a,,4;3*5 b,,4- c,4 c,g,c~4 c,g,c1 c4;1 g,;2 c,;3 g,;2 c,c1;31"
y <- as_music(y)

## Not run: 
if(tabr_options()$lilypond != ""){ # requires LilyPond installation
  plot_music(x)
  plot_music(x, "treble_8", tab = TRUE)

  plot_music_tc(x)
  plot_music_bc(x)

  plot_music_tab(x)
  plot_music_guitar(x)
  plot_music_bass(y)
}
