umxFixAll: Fix all free parameters

Description

Fix all free parameters in a model using omxGetParameters()

Usage

umxFixAll(model, name = "_fixed", run = FALSE, verbose = FALSE)

Arguments

model	an OpenMx::mxModel() within which to fix free parameters
name	optional new name for the model. if you begin with a _ it will be made a suffix
run	whether to fix and re-run the model, or just return it (defaults to FALSE)
verbose	whether to mention how many paths were fixed (default is FALSE)

Value

• the fixed OpenMx::mxModel()

Examples

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

m1 = umxRAM("OneFactor", data = demoOneFactor, type = "cov",
	umxPath("G", to = manifests),
	umxPath(var = manifests),
	umxPath(var = "G", fixedAt = 1)
)
m2 = umxFixAll(m1, run = TRUE, verbose = TRUE)
mxCompare(m1, m2)
