Common Interval
This function finds the common interval on a set of tree-ring widths
such as that produced by read.rwl.
common.interval(rwl, type=c("series", "years", "both"),
make.plot=TRUE)rwl |
a |
type |
a |
make.plot |

This trims an rwl object to a common interval that maximizes
the number of series (type="series"), the number of years
(type="years"), or a compromise between the two
(type="both"). A modified seg.plot can be drawn
as well.
A data.frame with colnames(x) and
rownames(x).
