R Documentation

Resolve a numeric contrast weight vector to full group-level order

Description

Expands a (possibly level-named or level-length) numeric weight vector into a full vector over all group levels in factor order, validating that it references known levels, sums to zero and is not trivially zero.

Usage

resolve_contrast_weights(x, orig_levels)

Arguments

`x`	Numeric weight vector, either named by group levels (missing levels are filled with `0`) or of length `length(orig_levels)` in factor order.
`orig_levels`	Character vector of the group factor levels (in order).
