Manipulate SIGMA matrices

The primary function is smat that can be used to both get the $SIGMA matrices out of a model object and to update $SIGMA matrices in a model object.

smat(.x, ...)

# S4 method for missing
smat(.x, ...)

# S4 method for matrix
smat(.x, ..., labels = list())

# S4 method for list
smat(.x, ...)

# S4 method for sigmalist
smat(.x, ...)

# S4 method for mrgmod
smat(.x, ..., make = FALSE, open = FALSE)

# S4 method for `NULL`
smat(.x, ...)

# S4 method for mrgsims
smat(.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 $SIGMA 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("sigma")
mat1 <- matrix(1)
mat2 <- diag(c(1,2))
mat3 <- matrix(c(0.1, 0.002, 0.002, 0.5), 2,2)
mat4 <- dmat(0.1, 0.2, 0.3, 0.4)
