Extract the primary shared gene axis from a Stage 1 result

Source: R/08-contracts.R, R/04a-decomposition-result.R
shared_axis.Rd

Returns the j-th column of the gene loading matrix from a DecompositionResult. Defaults to the first (primary shared) axis. This is the contract-level semantic accessor — callers should prefer this over reaching into dr_V_k() directly.

Usage

shared_axis(x, j = 1L)

# S4 method for class 'DecompositionResult'
shared_axis(x, j = 1L)

Arguments

x

a DecompositionResult

j

integer column index (default 1L — the primary shared axis)

Value

numeric vector of length p (one gene loading per feature)
