In datashield/dsMxClient: Datashield package for advanced structural equation modelling

Description Usage Arguments Details Value Author(s) References Examples

This function is similar to OpenMx function mxEval.

1 2	ds.mxEval(expression = NULL, model = NULL, compute = FALSE, show = FALSE, defvar.row = 1, cacheBack = FALSE, datasources = NULL)

`expression`	a string character an arbitrary R expression.
`model`	a string character, the name of the model in which to evaluate the expression.
`compute`	a boolean, if TRUE then compute the value of algebra expressions.
`show`	if TRUE then print the translated expression.
`defvar.row`	an integer, the row number for definition variables when compute=TRUE.
`cacheBack`	a boolean, if TRUE then return the list pair (value, cache).
`datasources`	a list of opal object(s) obtained after login in to opal servers; these objects hold also the data assign to R, as `dataframe`, from opal datasources. By default an internal function looks for 'opal' objects in the environment and sets this parameter.

See details of the OpenMx function 'mxModel' in the package OpenMx.

the evaluation of an expression.
