omega: Manipulate OMEGA matrices

Description

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.

Usage

omat(.x, ...)
# S4 method for missing
omat(.x, ...)
# S4 method for matrix
omat(.x, ..., labels = list())
# S4 method for NULL
omat(.x, ...)
# S4 method for list
omat(.x, ...)
# S4 method for omegalist
omat(.x, ...)
# S4 method for mrgmod
omat(.x, ..., make = FALSE, open = FALSE)
# S4 method for 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.

Examples

# example("omega")
mat1 <- matrix(1)
mat2 <- diag(c(1,2,3))
mat3 <- matrix(c(0.1, 0.002, 0.002, 0.5), 2,2)
mat4 <- dmat(0.1, 0.2, 0.3, 0.4)

omat(mat1)
omat(mat1, mat2, mat3)
omat(A = mat1, B = mat2, C = mat3)

mod <- mrgsolve::house() %>% omat(mat4)

omat(mod)
omat(mod, make = TRUE)
as.matrix(omat(mod))
