The S4 methods for x
of type matrix
,
array
, or numeric
call
matrixStats::rowAnyNAs
/ matrixStats::colAnyNAs
.
Returns a logical
vector
of length N (K).
matrixStats::rowAnyNAs()
and
matrixStats::colAnyNAs()
which are
used when the input is a matrix
or numeric
vector.
For checks if any element is equal to a value, see
rowAnys()
.
