The S4 methods for x
of type matrix

array
, or numeric
call
matrixStats::rowAnys
/ matrixStats::colAnys
.
Returns a logical
vector
of length N (K).
matrixStats::rowAnys()
and
matrixStats::colAnys()
which are
used when the input is a matrix
or numeric
vector.
For checks if all elements are equal to a value, see
