accidental: Extract accidental from pitch.

In Computational-Cognitive-Musicology-Lab/humdrumR: humdrumR

Extract accidental from pitch.

Description

Use this if you want to extract only the accidentals from pitch data, discarding octave and step information. Set explicitNaturals = FALSE if you don't want explicit naturals.

Usage

accidental(
  x,
  ...,
  generic = FALSE,
  simple = FALSE,
  octave.relative = FALSE,
  Key = NULL,
  transposeArgs = list(),
  parseArgs = list(),
  gamutArgs = list(),
  inPlace = FALSE
)

Arguments

x	Input data to parse as pitch information. The x argument can be any (atomic) vector, or a tonalInterval, or NULL.
...	Arguments passed to the pitch deparser. There are also two hidden (advanced) arguments you can specify: memoize and deparse (see the details below).
generic	Should "specific" pitch information (accidentals and qualites) be discarded? Defaults to FALSE. Must be a singleton logical value: an on/off switch.
simple	Should "compound" pitch information (octave/contour) be discarded? Defaults to FALSE. Must be a singleton logical value: an on/off switch.
Key	The input Key used by the parser, deparser, and transposer. Defaults to NULL. Must be a diatonicSet or something coercable to diatonicSet; must be either length 1 or length(x)
transposeArgs	An optional list of arguments passed to a special transpose() call. Defaults to an empty list(). Must be a list of named arguments to transpose().
parseArgs	An optional list of arguments passed to the pitch parser. Defaults to an empty list(). Must be a list of named arguments to the pitch parser.
inPlace	Should non-pitch information be retained in the output string. Defaults to FALSE. Must be a singleton logical value: an on/off switch. This argument only has an effect if the input (the x argument) is character strings, and there is extra, non-pitch information in the input strings "besides" the pitch information. If so, and inPlace = TRUE, the output will be placed into an output string beside the original non-pitch information. If inPlace = FALSE, only the pitch output information will be returned (details below).
