Very handy function to modify the attributes of matrix cells in a model.

Table of Contents

note: This function cannot modify parameters that have NA labels (i,e, label your matrix cells if you want to use this to set and drop parameters.

**Usage**

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

**Arguments**

**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.

A <- mxMatrix('Full', 3, 3, labels = c('a','b', NA), free = TRUE, name = 'A') model <- mxModel(A, name = 'model') model <- omxSetParameters(model, c('a', 'b'), values = c(1, 2)) # set value of cells labelled "a" and "b" to 1 and 2 respectively model <- omxSetParameters(model, c('a', 'b'), newlabels = c('b', 'a')) # set label of cell labelled "a" to "b" and vice versa
