mxEval

Hi,

I'm doing something wrong when trying to use mxEval to inspect values. Part of the bivariate script I'm running is below. It outputs estimates accordingly (only copied the first couple). But when I try mxEval after running the model, I get the starting value:

> mxEval(ACE.a[1,1],multiCholACEModel,T,T)
multiCholACEModel[["ACE.a"]]@values[1, 1, drop = FALSE]
[,1]
[1,] 0.5

Can someone tell me what I'm doing wrong?

Many thanks and Happy Easter to all.

Paul
