blockmatrix {blockmatrix} | R Documentation |
This function builds a blockmatrix
blockmatrix(dim, value = NULL, names = NULL, list = NULL, use.as.blockmatrix = TRUE, adjust_zero = TRUE, add_zero_matrix = FALSE, zero_element = "0", ...)
dim |
dimension of a block-matrix |
value |
matrix containing the indices (names) of
blockmatrix element. If missing, it is |
names |
charcarcter vector containing the names for each matrix-type element of the block-matrix |
list |
list containing the matrices to be inserted
into the block-matrix. If |
use.as.blockmatrix |
logical value. If |
adjust_zero,add_zero_matrix,zero_element |
arguments
passed to |
... |
elements of the block-matrix. |
