Absolute Median Normalization

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.

Usage

normalize_median_abs(x)

# S3 method for class 'glyexp_experiment'
normalize_median_abs(x)

# S3 method for class 'matrix'
normalize_median_abs(x)

# Default S3 method
normalize_median_abs(x)

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.
