umx_set_checkpoint: umx_set_checkpoint

Description

Set the checkpoint status for a model or global options

Usage

umx_set_checkpoint(interval = 1, units = c("evaluations", "iterations",
  "minutes"), prefix = "", directory = getwd(), model = NULL)

Arguments

interval

How many units between checkpoints: Default = 1. A value of zero sets always to 'No' (i.e., do not checkpoint all models during optimization)

units

units to count in: Default unit is 'evaluations' ('minutes' is also legal)

prefix

string prefix to add to all checkpoint filenames (default = "")

directory

a directory, i.e "~/Desktop" (defaults to getwd())

model

(optional) model to set options in (default = NULL)

Value

- mxModel if provided
