again, pardon intrusions from an R neophyte.
this works
thisOMxModel <- mxModel("thisOMxModel", mxMatrix(name='VA', type='Symm', free=TRUE, nrow=8, ncol=8) )
but this does not
thatOMxModel <- new("MxModel")
thatOMxModel <- mxModel(thatOMxModel, mxMatrix(name='VA', type='Symm', free=TRUE, nrow=8, ncol=8) )
