lotri (version 1.0.0)

lotriMat: Create a matrix from a list of matrices

Description

This creates a named banded symmetric matrix from a list of named symmetric matrices.

Usage

lotriMat(matList, format = NULL, start = 1L)

Value

Named symmetric block diagonal matrix based on concatenating the list of matrices together

Arguments

matList

list of symmetric named matrices

format

The format of dimension names when a sub-matrix is repeated. The format will be called with the dimension number, so "ETA[%d]" would represent "ETA[1]", "ETA[2]", etc

start

The number the counter of each repeated dimension should start.

Examples

testList <- list(lotri({et2 + et3 + et4 ~ c(40,
                           0.1, 20,
                           0.1, 0.1, 30)}),
                 lotri(et5 ~ 6))

testList

lotriMat(testList)


# Another option is to repeat a matrix a number of times.  This
# can be done with list(matrix, # times to repeat).

# In the example below, the first matrix is repeated 3 times
testList <- list(list(lotri({et2 + et3 + et4 ~ c(40,
                           0.1, 20,
                           0.1, 0.1, 30)}), 3),
                 lotri(et5 ~ 6))

lotriMat(testList)

# Notice that the dimension names `et2`, `et3` and `et4` are
# repeated.

# Another option is to name the dimensions.  For example it could
# be `ETA[1]`, `ETA[2]`, etc by using the 'format' option:

lotriMat(testList, "ETA[%d]")

# Or could start with ETA[2]:

lotriMat(testList, "ETA[%d]", 2)
