residuals.MxModel: Get residuals from an MxModel

In tbates/umx: Structural Equation Modeling and Twin Modeling in R

Get residuals from an MxModel

Description

Return the residuals() from an OpenMx RAM model. You can format these (with digits), and suppress small values.

Usage

## S3 method for class 'MxModel'
residuals(object, digits = 2, suppress = NULL, reorder = NULL, ...)

Arguments

object	An fitted OpenMx::mxModel() from which to get residuals
digits	round to how many digits (default = 2)
suppress	smallest deviation to print out (default = NULL = show all)
reorder	optionally reorder the variables in the residuals matrix to show patterns
...	Optional parameters

Value

• matrix of residuals

Examples

## Not run: 
require(umx)
data(demoOneFactor)
manifests = names(demoOneFactor)

m1 = umxRAM("One Factor", data = demoOneFactor, type = "cov",
	umxPath("G", to = manifests),
	umxPath(var = manifests),
	umxPath(var = "G", fixedAt = 1.0)
)

# residuals are returned as an invisible object you can capture in a variable
