Create age depth models

Description

Create age depth models

Usage

age_depth_model(
  .data = NULL,
  depth,
  age,
  age_min = NA_real_,
  age_max = NA_real_,
  interpolate_age = age_depth_interpolate,
  extrapolate_age_below = ~age_depth_extrapolate(.x, .y, x0 = last, y0 = last),
  extrapolate_age_above = ~age_depth_extrapolate(.x, .y, x0 = first, y0 = first),
  interpolate_age_limits = age_depth_exact,
  extrapolate_age_limits_below = age_depth_na,
  extrapolate_age_limits_above = age_depth_na
)

Arguments

.data	A data frame
depth, age, age_min, age_max	Expressions evaluated in .data that provide the known depths, known ages, and error information if available. These expressions are evaluated like they are within mutate if .data is present.
interpolate_age, extrapolate_age_below, extrapolate_age_above	These arguments provide the rules for interpolating and extrapolating ages based on depths.
interpolate_age_limits, extrapolate_age_limits_below, extrapolate_age_limits_above	These arguments provide the rules for interpolating and extrapolating age min and max values based on depths.

Value

An age depth model object.

Examples

age_depth_model(
  alta_lake_210Pb_ages,
  depth = depth_cm, age = age_year_ad,
  age_max = age_year_ad + age_error_yr,
  age_min = age_year_ad - age_error_yr
)
