| omxSetParameters {OpenMx} | R Documentation |
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, strict = TRUE)
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. |
strict |
boolean. if TRUE then throw an error when a label does not appear in the model. |
