vsn2(x) with x being an ExpressionSet.
Slots
par:- A 3D array of size (number of strata) x (number of
columns of the data matrix) x 2 containing fitted normalization parameters
(see vignette).
n:- An integer scalar containing n,
the number of rows of the data matrix.
strata:- A factor of length 0 or n. If its length is
n, then its levels correspond to different normalization strata
(see vignette).
refh:- A numeric vector of length 0 or n. If its length
is n, then these are the fitted parameters $hat{μ}_k$, $k=1,...,n$.
refsigma:- A numeric scalar, $hat{σ}$.
hx:- A numeric matrix with 0 or n rows. If the number of
rows is n, then
hx contains the transformed data matrix.
