reduce pre-paleoTS format to paleoTS

paleoTS is a format for paleontological time series. It is a summary format where interpopulation variance is provided as a parameter. As a result, taphonomic and ecological effects that act on individual specimens can not be modeled for paleoTS objects. To resolve this, the pre_paleoTS format tracks each specimen individually. This function reduces the pre-paleoTS format into standard paleoTS object, which can be used by the paleoTS package.

Usage

reduce_to_paleoTS(x, min_n = 1, na.rm = TRUE, ...)

Arguments

x

a pre_paleoTS object

min_n

minimum number of specimens. If the number of specimens at a sampling location falls below this number, the sampling location will be removed

na.rm

Logical. If sampling locations are NA (e.g., because of erosion), should the sample be removed?

...

other options. currently unused

Value

a paleoTS object

• stasis_sl(), strict_stasis_sl, random_walk_sl, and ornstein_uhlenbeck_sl() to simulate trait evolution on specimen level (sl), returning an object of type pre_paleoTS

Examples

x = stasis_sl(t = 0:5)     # create pre_paleoTS object representing stasis on specimen level
y = reduce_to_paleoTS(x)   # reduce to standard paleoTS format
plot(y)

# now analyses using the paleoTS package can be applied to y
