In bsaul/elktoeChemistry: Data and code for Elktoe Chemistry project

Create a function that identifies annual layers based on distance

Description

This creates a function that determines annuli layers:

• only for transects that cross the nacre

• only up to the ncr_psm transition

• in the case that no annuli measurements exist the annual layer is labeled "U" for unknown

Usage

create_annuli_idFUN(.data, .reference_transition = "on_")

Arguments

.data	a measurement dataset (for a single id_transect)
.reference_transition	the transition between layer to use as the reference. Defaults to "on_" (the transition from "laser on" to the next layer). "ipx_" is the transition from inner epoxy to the next layer (either nacre or prismatic layer depending on the location of the transect)

Value

a function of x that cuts x based on the distances measured between annuli
