multiplsrog_loading: Multiset partial least squares rank order of groups loading

In loadings: Loadings for Principal Component Analysis and Partial Least Squares

Multiset partial least squares rank order of groups loading

Description

This function computes multiset partial least squares rank order of groups (PLS-ROG) loading from the result of the "multipls_rog" function.

Usage

multiplsrog_loading(multiplsrog)

Arguments

multiplsrog

The following variables (P,T,Q and U) are included in the multiplsrog object. P : A list of matrix with Multiset PLS-ROG coefficients for the explanatory variables in each column for each dataset T : A list of matrix with Multiset PLS-ROG scores for the explanatory variables in each column for each dataset Q : A matrix with Multiset PLS-ROG coefficients for the response variable in each column U : A matrix with Multiset PLS-ROG scores for the response variable in each column tau : Matrix for strength parameter of the connection between omics datasets or between omics dataset and group information.

Details

The multiset PLS-ROG loading and the p-value by statistical hypothesis testing is added to the multiplsrog object returned by the "multipls_rog" function in this package.

Value

The return value is a list object that contains the following elements:

Score : A list of matrix with Multiset PLS score for auxiliary variable in each column for each dataset

R : A list of matrix with Multiset PLS-ROG loadings in each column for each dataset

p.value : A list of matrix with p-value of multiset PLS-ROG loading in each column for each dataset

D <- whhl$D
tau <- whhl$tau

multiplsrog <- multipls_rog(X,Y,tau,D)
# multiplsrog <- multipls_rog(X,Y,tau,D, kappa=0.999)

multiplsrog <- multiplsrog_loading(multiplsrog)
