shift_negative_values: Shift negative values in a matrix

In ParkerICI/grappolo: Feature generation from single-cell data

Description

This function shifts negative values in a data matrix. For each column vector the procedure is as follows:

1. A specific quantile is calculated from the vector

2. If the quantile is negative then its absolute value is added to the vector

3. Values that are still negative are truncated at 0

Usage

shift_negative_values(m, quantile.prob)

Arguments

m	The data matrix
quantile.prob	The quantile probability to use

Value

Return the transformed data matrix
