rowMads {MatrixGenerics} | R Documentation |
Calculates the median absolute deviation for each row (column) of a matrix-like object.

call
matrixStats::rowMads
/ matrixStats::colMads
.
Returns a numeric
vector
of length N (K).
matrixStats::rowMads()
and
matrixStats::colMads()
which are used
when the input is a matrix
or numeric
vector.
For non-robust standard deviation estimates, see
rowSds()
