Coerce to an observed trajectory

Generic converting the supported observation representations to an obs_traj object.

Usage

as_obs(x, ...)

# S3 method for class 'obs_traj'
as_obs(x, ...)

# S3 method for class 'matrix'
as_obs(x, dt = 1, t0 = 0, ...)

# S3 method for class 'aci_sim'
as_obs(x, ...)

Arguments

x

Object to coerce: an obs_traj, a numeric matrix, or a simulation of class aci_sim.

...

Arguments passed to methods.

dt

Positive 1-length numeric step used to build the time grid.

t0

1-length numeric time of the first observation.

Value

An object of class obs_traj; see observed_trajectory().

Methods (by class)

• as_obs(obs_traj): Returns the trajectory unchanged.

• as_obs(matrix): Builds a uniform grid from dt and t0 for a matrix of observations.

• as_obs(aci_sim): Extracts the observation component of a simulation.

Examples

m <- aci_dyad_model()
sim <- simulate(m, seed = 1, t_end = 2, dt = 0.01)
ob <- as_obs(sim)
as_obs(sim)
#> <obs_traj> k = 1, N+1 = 201, dt = 0.01, span [0, 2]
