x |
an object of class |
depths |
depths, if different from those provided in x. |
breaks |
breaks from which to calculate interpolated rates. |
per.capita |
logical. Whether the origination and extinction rates should be given as fractions of the standing diversity. |
remove.below |
remove species that occur only this number or fewer levels. |

If depths
is provided, it will clobber x$depths
, should x$depths
exist.
oe.rates
returns a list of $basic,
which is a data frame with columns stand.div, orig and ext giving standing diversity, origination and extinction rates at the sampled depths/times; $bx,
which are the boundary crossers at each sampled depth/time; $intervals,
which gives the lengths of each interval (in depth or time); and $interpol,
which gives interpolated rates per time as calculated by Foote(2000b).
