S3 Method to plot objects of class fs.n1.class. Graphic display of the number of unique subsamples produced by multiple Forward Searches.

## S3 method for class 'fs.n1.class'
plot(
 x,
 cutoff=default.cutoff,
 n1.type=default.type,
 lwd=default.lwd,
 lty=default.lty,
 col=default.col,
 ylim = default.ylim, 
 xlim = default.xlim,
 ...)

`x`	Object of `class fs.n1.class` produced by `fs.MSA.n1`.
`cutoff`	Default is the cutoff used for determining n1 in `fs.MSA.n1`.
`n1.type`	Default is "unique" which shows number of unique subsamples; "major" shows the number of subsamples not belonging to largest unique subsample; "both" plots both unique and major.
`lwd`	Line width
`lty`	Line type
`col`	Colour to be used for the lines.
`ylim, xlim`	Range of `x` and `y` values with sensible defaults.
`...`	Other arguments are ignored.

Returns a graph.
