Normalize the expression matrix by dividing each column (sample) by the absolute
median of that column (NA ignored), so that the absolute median of each column is 1.
Arguments
- x
Either a glyexp_experiment
object or a matrix.
If a matrix, rows should be variables and columns should be samples.
Value
Returns the same type as the input. If x
is a glyexp_experiment
,
returns a glyexp_experiment
with normalized expression matrix.
If x
is a matrix, returns a normalized matrix.
