Manipulate OMEGA matrices

Source: R/matlist.R

The primary function is omat() that can be used to both get the $OMEGA matrices out of a model object and to update $OMEGA matrices in a model object.

omat(.x, ...)

# S4 method for class 'missing'
omat(.x, ...)

# S4 method for class 'matrix'
omat(.x, ..., labels = list())

# S4 method for class 'NULL'
omat(.x, ...)

# S4 method for class 'list'
omat(.x, ...)

# S4 method for class 'omegalist'
omat(.x, ...)

# S4 method for class 'mrgmod'
omat(.x, ..., make = FALSE, open = FALSE)

# S4 method for class 'mrgsims'
omat(.x, make = FALSE, ...)

Arguments

.x

a matrix, list of matrices or matlist object.

...

passed to other functions, including modMATRIX().

labels

character vector of names for $OMEGA elements; must be equal to number of rows/columns in the matrix.

make

logical; if TRUE, matrix list is rendered into a single matrix.

open

passed to merge.list().

x

matlist object.
