covariate_interp {anipaths}

Synchronous interpolation of covariate using either GAM (same as paths) or piece-wise constant if covariate is a factor

Description

Synchronous interpolation of covariate using either GAM (same as paths) or piece-wise constant if covariate is a factor

Usage

covariate_interp(paths, covariate = NULL, Time.name, time.grid, s_args)

Arguments

paths

lists of data.frames containing positions, times, and covariate for each individual

covariate

character string giving name of covariate variable in data.frames

Time.name

character string giving name of time variable in data.frames

time.grid

grid of possible times to use for interpolation (individuals will only be interpolated to times within the range of observation times)

s_args

arguments to mgcv::s() for GAM interpolation method

Value

list of interpolated covariate by individual
