Hi,
Why is the mxConstraint command not working anymore?
How else is one to constrain the variances to unity?
Thanks.

Algebra to compute total variances and standard deviations (diagonal only)
mxAlgebra( expression=A+C+E, name="V" ),
mxMatrix( type="Iden", nrow=nv, ncol=nv, name="I"),
mxAlgebra( expression=solve(sqrt(I*V)), name="sd"),
Constraint on variance of ordinal variables
mxConstraint( alg1="V", "=", alg2="I", name="Var1"),
Error in mxConstraint(alg1 = "V", "=", alg2 = "I", name = "Var1") :
unused argument(s) (alg1 = "V", alg2 = "I")
