# defl.select: deflation function In RGCCA: Regularized and Sparse Generalized Canonical Correlation Analysis for Multiblock Data

## Description

The function defl.select() computes residual matrices X_{1,h+1}, …, X_{J,h+1}. These residual matrices are determined according to the following formula: X_{j,h+1} = X_{jh} - y_{jh} p_{jh}^t.

## Usage

 1 defl.select(yy, rr, nncomp, nn, nbloc)

## Arguments

 yy A matrix that contains the SGCCA block components of each block: y_{1h}, …, y_{Jh} rr A list that contains the residual matrices X_{1h}, …, X_{Jh} nncomp A 1 \times J vector that contains the number of components to compute for each block. nn A 1 \times J vector that contains the numbers of already computed components for each block nbloc Number of blocks.

## Value

 resdefl A list of J elements that contains X_{1,h+1}, …, X_{J,h+1}. pdefl A list of J elements that contains p_{1h}, …, p_{Jh}.
