Plots the residual track computed at regular interval during the fit of the NMF model x.

Usage

S4 (NMFfit,missing)
`plot`(x, y, skip = -1, ...)

Arguments

skip

an integer that indicates the number of points to skip/remove from the beginning of the curve. If skip=1L (default) only the initial residual -- that is computed before any iteration, is skipped, if present in the track (it associated with iteration 0).

x

the coordinates of points in the plot. Alternatively, a single plotting structure, function or any R object with a plot method can be provided.

y

the y coordinates of points in the plot, optional if x is an appropriate structure.

...

Arguments to be passed to methods, such as graphical parameters (see par). Many methods will accept the following arguments:

1. typewhat type of plot should be drawn. Possible types are
   • "p" for points,
   • "l" for lines,
   • "b" for both,
   • "c" for the lines part alone of "b",
   • "o" for both ‘overplotted’,
   • "h" for ‘histogram’ like (or ‘high-density’) vertical lines,
   • "s" for stair steps,
   • "S" for other steps, see ‘Details’ below,
   • "n" for no plotting.
   All other types give a warning or an error; using, e.g., type = "punkte" being equivalent to type = "p" for S compatibility. Note that some methods, e.g. plot.factor, do not accept this.
2. mainan overall title for the plot: see title.
3. suba sub title for the plot: see title.
4. xlaba title for the x axis: see title.
5. ylaba title for the y axis: see title.
6. aspthe y/x aspect ratio, see plot.window.
