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.

Examples


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
