The function calculates points in time where large changes happen in the isotopic values. It uses the posterior distributions to estimate the probability of changes to be (absolutely or relatively) large.

boolean. If the calculation shall be based on absolute or relative differences. Defaults to TRUE.
numeric. The threshold for a shift to be considered "large". Defaults to 1.5 for absolute isotopic values and 15 percent for relative changes.
the probability for the differences to be larger than the threshold. Defaults to 50 percent.
a data.frame containing the interval starts (intStart) and ends (intEnd) of changes.
