createXblocks: Create list of paired data blocks

In multiridge: Fast Cross-Validation for Multi-Penalty Ridge Regression

Create list of paired data blocks

Description

Create list of paired data blocks

Usage

createXblocks(datablocks, which2pair = NULL)

Arguments

datablocks	List of data frames or matrices representing b=1,...,B data blocks of dimensions n x p_b.
which2pair	Integer vector of size 2 (or NULL)

Details

Only use this function when you wish to pair two data blocks. If which2pair = NULL the output matches the input. If not, the function adds a paired data block, pairing the two data blocks corresponding to the elements of which2pair.

Value

List. Same length as datablocks when which2pair = NULL, or augmented with one paired data block.
