This function performs an approximate log-transformation (base e) of a `paleoTS`

object.

1 | ```
ln.paleoTS(y)
``` |

`y` |
a paleontological time series |

For a random variable x, its approximate mean on a log scale is the log of its untransformed mean. The approximate variance on a log scale is equal to the squared coefficient of variation.

the converted `paleoTS`

object.
