Rotate SVD components to make dominant directions positive

Source: R/solvers.R
rotateSVD.Rd

Ensures consistency in SVD output by flipping signs so that each left singular vector has a majority of positive entries.

Usage

rotateSVD(svdres)

Arguments

svdres

A list as returned by svd(), with components u, d, and v.

Value

A modified svd-result list where each column of $u has been sign-flipped so that its entries sum to a nonnegative value; $v is flipped correspondingly.
