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