umx_check_model: umx_check_model

Description

Check an OpenMx model

Usage

umx_check_model(obj, type = NULL, hasData = NULL, beenRun = NULL, hasMeans = NULL, checkSubmodels = FALSE)

Arguments

obj

an object to check

type

what type the model must be, i.e., "RAM", "LISREL", etc. (defaults to not checking NULL)

hasData

whether the model should have data or not (defaults to not checking NULL)

beenRun

whether the model has been run or not (defaults to not checking NULL)

hasMeans

whether the model should have a means model or not (defaults to not checking NULL)

checkSubmodels

whether to check submodels (not implemented yet) (default = FALSE)

Value

- boolean

Examples

latents  = c("G")
manifests = names(demoOneFactor)
m1 <- mxModel("One Factor", type = "RAM", 
	manifestVars = manifests, latentVars = latents, 
	mxPath(from = latents, to = manifests),
	mxPath(from = manifests, arrows = 2),
	mxPath(from = latents, arrows = 2, free = FALSE, values = 1.0),
	mxData(cov(demoOneFactor), type = "cov", numObs = 500)
)
umx_check_model(m1)
umx_check_model(m1, type = "RAM") # equivalent to umx_is_RAM()
umx_check_model(m1, hasData = TRUE)
## Not run: 
# umx_check_model(m1, hasMeans = TRUE)
# umx_check_model(m1, beenRun = FALSE)
# ## End(Not run)
