Reconstruct fitted or subsetted outputs for a regress object

For regression-based bi_projectors, reconstruction should map from the design matrix side (scores) to the output space using the regression coefficients, without applying any reverse preprocessing (which belongs to the input/basis side).

Usage

# S3 method for class 'regress'
reconstruct(
  x,
  comp = seq_len(ncomp(x)),
  rowind = 1:nrow(scores(x)),
  colind = 1:nrow(x$coefficients),
  ...
)

Arguments

x

A regress object produced by regress().

comp

Integer vector of component indices (columns of the design matrix / predictors) to use.

rowind

Integer vector of row indices in the design matrix (observations) to reconstruct.

colind

Integer vector of output indices (columns of Y) to reconstruct.
