Crossdate an undated series
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 |

This takes an undated series (a floater) and drags it along a dated rwl object in order to estabish possible dates for the series. This function is experimental and under development. It might change in future releases.
By default a data.frame is returned with the first and last year of the period compared as well as the correlation, p-value, and number of observations. If return.rwl is TRUE then a list is returned with the rwl object as well as the data.frame with the correlation statistics.
