R: Create an object params_process

params_process {PhylogeneticEM} | R Documentation

## Create an object params_process

### Description

`params_process` creates or extracts a set of parameters of class `params_process`.

### Usage

    params_process(x, ...)

### Arguments

`x` | an S3 object.
`...` | further arguments to be passed to the specific method.

### Value

An S3 object of class `params_process`. This is essentially a list containing the following entries:

process

  The model used. One of "BM" (for a full BM model, univariate or multivariate); "OU" (for a full OU model, univariate or multivariate); or "scOU" (for a "scalar OU" model).

p

  Dimension of the trait.

root.state

  List describing the state of the root, with:

  random

    random state (TRUE) or deterministic state (FALSE)

  value.root

    if deterministic, value of the character at the root

  exp.root

    if random, expectation of the character at the root

  var.root

    if random, variance of the character at the root (pxp matrix)

shifts

  List with position and values of the shifts:

  edges

    vector of the K id of edges where the shifts are

  values

    matrix p x K of values of the shifts on the edges (one column = one shift)

  relativeTimes

    vector of dimension K of relative time of the shift from the parent node of edges

variance

  Variance-covariance matrix size p x p.

selection.strength

  Matrix of selection strength size p x p (OU).

optimal.value

  Vector of p optimal values at the root (OU).
