Plots a tree-ring series with a master chronology and displays their fit, segments, and detrending options in support of the cross-dating functions.

series.rwl.plot(rwl, series, series.yrs = as.numeric(names(series)),
                seg.length = 100, bin.floor = 100, n = NULL,
                prewhiten = TRUE, biweight = TRUE, floor.plus1 = FALSE)

`rwl`	a `data.frame` with series as columns and years as rows such as that produced by `read.rwl`.
`series`	a `numeric` or `character` vector. Usually a tree-ring series. If the length of the value is 1, the corresponding column of `rwl` is selected (by name or position) as the series and ignored when building the master chronology. Otherwise, the value must be `numeric`.
`series.yrs`	a `numeric` vector giving the years of `series`. Defaults to `as.numeric(names(series))`. Ignored if `series` is an index to a column of `rwl`.
`seg.length`	an even integral value giving length of segments in years (e.g., 20, 50, 100 years).
`bin.floor`	a non-negative integral value giving the base for locating the first segment (e.g., 1600, 1700, 1800 AD). Typically 0, 10, 50, 100, etc.
`n`	`NULL` or an integral value giving the filter length for the `hanning` filter used for removal of low frequency variation.
`prewhiten`	`logical` flag. If `TRUE` each series is whitened using `ar`.
`biweight`	`logical` flag. If `TRUE` then a robust mean is calculated using `tbrm`.
`floor.plus1`	`logical` flag. If `TRUE`, one year is added to the base location of the first segment (e.g., 1601, 1701, 1801 AD).

The function is typically invoked to produce four plots showing the effect of the detrending options n and prewhiten and the binning options seg.length and bin.floor.

Plot 1: Time series plot of the filtered series and the master
Plot 2: Scatterplot of series vs. master
Plot 3: Segments that would be used in the other cross-dating functions (e.g., corr.series.seg)
Plot 4: Text giving the detrending options and the time span of the raw and filtered series and master

The series and master are returned as well.

See help pages for corr.rwl.seg, corr.series.seg, and ccf.series.rwl for more information on these arguments.

A list containing the filtered vectors series and master.
