Interpolate Data

Description

Interpolates data over a specified age range and timestep using a method.

Usage

interpolate_data(
  data = NULL,
  by = "dataset_name",
  age_var = "age",
  value_var = "pollen_prop",
  method = "linear",
  rule = 1,
  ties = mean,
  age_min = 0,
  age_max = 12000,
  timestep = 500
)

Arguments

data

A data frame containing the data to be interpolated.

age_var

Name of the age variable column (default: "age").

value_var

Name of the value variable column (default: "pollen_prop").

method

Interpolation method to use (default: "linear").

rule

Integer specifying the extrapolation rule (default: 1).

ties

Function to handle tied values (default: ‘mean’).

age_min

Minimum age for interpolation (default: 0).

age_max

Maximum age for interpolation (default: 12000).

timestep

Timestep for interpolation (default: 500).

Details

Nests data by dataset and taxon, performs interpolation using ‘stats::approx’, and returns the interpolated data in a flat format.

Value

A data frame with interpolated values, including dataset name, taxon, age, and value columns.
