R: Remove all instances of data from a model

omxModelDeleteData {OpenMx} | R Documentation

## 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

`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)
    object.size(factorFit)
    factorFit$data
