\name{omxModelDeleteData}
\alias{omxModelDeleteData}
\title{Remove all instances of data from a model}
\description{
For very large data, it can be desirable to discard data after the model
is run. That is what the purpose of this function.
Data is discarded from the model and all submodels recursively.
}
\usage{
omxModelDeleteData(model)
}
\arguments{
\item{model}{a MxModel object.}
}
\examples{
library(OpenMx)
data(demoOneFactor)
manifests <- names(demoOneFactor)
latents <- c("G")
factorModel <- mxModel(model="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)
)
factorFit <-mxRun(factorModel)
object.size(factorFit)
factorFit <- omxModelDeleteData(factorFit)
