Block-diagonal matrices can be extracted or removed using two small functions implemented here, in addition, non-square matrices are supported.

The stable version of the
diagonals package can be install from CRAN using:
The development version, to be used at your peril, can be installed using:
if (!require('devtools')) install.packages('devtools') devtools::install_github("bquast/diagonals")
Following installation, the package can be loaded using:
