melodyplot: Plotting a melody

Description Usage Arguments Author(s) See Also

Plot a observed melody and (optional) an expected melody, as well as corresponding energy values (corresponding to the loudness of the sound).

`object`	An object of class `Wspec`.
`observed`	Observed notes, probably as a result from `noteFromFF` (or a smoothed version). This should correspond to the `Wspec` `object`. It can also be a matrix of `k` columns where those `k` notes in the same row are displayed at the same timepoint.
`expected`	Expected notes (optional; in order to compare results), same format as `observed`.
`bars`	Number of bars to be plotted (a virtual static segmentation takes place). If `NULL` (default), time rather than bars are used.
`main`	Main title of the plot.
`xlab, ylab`	Annotation of -/y-axes.
`xlim, ylim`	Range of x-/y-axis, where `ylim` must be an integer that represents the range of note heights that should be displayed.
`observedtype`	Type (either `"p"` for points or `"l"` for lines) used for representing observed notes. `"l"` (the default) is not sensible for polyphonic representations.
`observedcol`	Colour for the observed melody.
`expectedcol`	Colour for the expected melody.
`gridcol`	Colour of the grid.
`lwd`	Line width, see `par` for details.
`las`	Orientation of axis labels, see `par` for details.
`cex.axis`	Size of tick mark labels, see `par` for details.
`mar`	Margins of the plot, see `par` for details.
`notenames`	Optionally specify other notenames (character) for the y axis.
`thin`	Amount of thinning of notenames, i.e. only each `thin`th notename is displayed on the y-axis.
`silence`	Character string for label of the ‘silence’ (default) axis.
`plotenergy`	Logical (default: `TRUE`), whether to plot energy values in the bottom part of the plot.
`...`	Additional graphical parameters to be passed to underlying `plot` function.
`axispar`	A named list of three other lists (`ax1`, `ax2`, and `ax4`) containing parameters passed to the corresponding `axis` calls for the three axis time (`ax1`), notes (`ax2`), and energy (`ax4`).
`boxpar`	A list of parameters to be passed to the box generating functions.
`energylabel`	A list of parameters to be passed to the energy-label generating `mtext` call.
`energypar`	A list of parameters to be passed to the `lines` function that draws the energy curve.
`expectedpar`	A list of parameters to be passed to the `rect` function that draws the rectangles for expected values.
`gridpar`	A list of parameters to be passed to the `abline` function that draws the grid lines.
`observedpar`	A list of parameters to be passed to the `lines` function that draws the observed values.
