These functions attach supplementary rows or columns to an ordination object.

recover_supp_cols(x)An object of class 'tbl_ord'.
Matrices having the same numbers of columns as returned by
recover_rows() and recover_cols(), or else NULL.
The recover_supp_*() S3 methods produce matrices of
supplemental rows or columns of a tbl_ord object from the object itself.
The motivating example is linear discriminant analysis, which produces a
natural biplot of class discriminant centroids and variable axes but is
usually supplemented with case discriminant scores. The supplementary values
are augmented with an .element column whose value indicates their source
and can be incorporated into a tidied form. If no supplementary
rows of a factor are produced, the functions return NULL.
