Description Usage Arguments Details Value Author(s) See Also Examples

Pulls an undated series through a dated rwl file in order to try to establish dates

xdate.floater(rwl, series, series.name = "Unk", min.overlap = 50, n = NULL,
             prewhiten = TRUE, biweight = TRUE,
             method = c("spearman", "pearson","kendall"),
             make.plot = TRUE,return.rwl = FALSE, verbose = TRUE)

`rwl`	a `data.frame` with series as columns and years as rows such as that produced by `read.rwl`.
`series`	a `data.frame` with series as columns and years as rows such as that produced by `read.rwl`.
`series.name`	a `character` giving a name for the series.
`min.overlap`	number
`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`.
`method`	Can be either `"pearson"`, `"kendall"`, or `"spearman"` which indicates the correlation coefficient to be used. Defaults to `"spearman"`. See `cor.test`.
`make.plot`	`logical flag` indicating whether to make a plot.
`return.rwl`	`logical flag` indicating whether to make a plot.
`verbose`	`logical flag` indicating whether to print some results to screen.
