chdir: Characteristic Direction

In Swarchal/charDirection: Principal Characteristic Direction

Description

Calculates the characteristic direction for a phenotypic dataset

Usage

chdir(ctrl, expm, samples, r = 1)

Arguments

ctrl	matrix of control data
expm	matrix of experiment (perturbed) data
samples	vector of drug names
r	numeric between 0 and 1. Regularised term, a parameter that smooths the covariance matrix and reduces potential noise in the dataset. The default value is 0, no regularisation.

Value

vector of n-components representing the characteristic direction of the dataset. n equals the number of features in the dataset. b is also a matrix object, and is sorted by its components' absolute values in descending order.
