The S4 methods for x
of type matrix
,
array
, or numeric
call
matrixStats::rowWeightedMedians
/ matrixStats::colWeightedMedians
.
Returns a numeric
vector
of length N (K).
matrixStats::rowWeightedMedians()
and
matrixStats::colWeightedMedians()
which are used when the input is a matrix
or numeric
vector.
See also rowMedians for the corresponding unweighted function.
