Create age depth models

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
)
#> <age_depth_model>
#> Call: 
#> age_depth_model(
#>   .data = alta_lake_210Pb_ages, depth = depth_cm,
#>   age = age_year_ad, age_min = age_year_ad - age_error_yr,
#>   age_max = age_year_ad + age_error_yr
#> )
