Assign Model Parameters


Modify the attributes of parameters in a model. This function cannot modify parameters that have NA labels.


omxSetParameters(model, labels, free = NULL, values = NULL,
	newlabels = NULL, lbound = NULL, ubound = NULL, indep = FALSE)


model a MxModel object.
labels a character vector of target parameter names.
free a boolean vector of parameter free/fixed designations.
values a numeric vector of parameter values.
newlabels a character vector of new parameter names.
lbound a numeric vector of lower bound values.
ubound a numeric vector of upper bound values.
indep boolean. set parameters in independent submodels.
