Class to contain input data and parameters for vsn functions
Description
Class to contain input data and parameters for vsn functions
Creating Objects
new("vsnInput")
Slots
x :A numeric matrix with the input data.
reference :An object of vsn ,
typically this would have been
obtained from a previous fit to a set of reference arrays (data).
strata :A factor of length 0 or n. If its length is
n, then its levels correspond to different normalization strata
(see vsn2 ).
ordered :Logical scalar; are the rows reordered so that
the strata are contiguous.
lts.quantile :Numeric scalar, seevsn2 .
subsample :Integer scalar, seevsn2 .
verbose :Logical scalar, seevsn2 .
calib Character of length 1, see manual page of vsn2 .
pstart :A 3D array of size (number of strata) x (number of
columns of the data matrix) x 2. It contains the start parameters.
optimpar :List with parameters for the numerical
optimiser L-BFGS-B ; see the manual page of vsn2 .
Methods
[ Subset
dim Get dimensions of data matrix.
