Description Usage Arguments Value Author(s) References Examples
Produce a composite serie from multiple charcoal records using bootstrap resampling, the sites charcoal values are binned and the mean in each bin is calculated prior the bootstrap procedure. This procedure is equivalent to Power et al. 2008.

TR |
An object returned by |
bins |
Numeric, the sequence for binning given in years (e.g. bins=seq(from=0, to=10000, by=200)). If unspecified the sequence is defined as bins=seq(from=min age, to=max age, by=median resolution). |
nboot |
Numeric, a number specifying the number of bootstrap replicates. |
binning |
Logical, set to TRUE (default) for binning, if transformed data are first interpolated this argument can be set to FALSE (no binning). |
conf |
Numeric, define confidence levels. |
