)
The dimensions of the matrix are 1-by-1 (all(dim(x) == 1)
) and
the sole value is a NA
These two situations correspond to matrices generated with either
new('matrix')
or matrix()
TRUE
if the matrix is empty otherwise FALSE
## Not run:
IsMatrixEmpty(new('matrix'))
IsMatrixEmpty(matrix())
IsMatrixEmpty(matrix(1:9, nrow = 3))
