get_contributions() returns a data.frame of contributions to the
definition of the principal dimensions.
get_correlations() returns a data.frame of correlations between
variables and dimensions. An extra column (named after sup_name)
is added specifying whether an observation is a supplementary point or
not.
get_cos2() returns a data.frame of \(cos^2\) values (i.e.
quality of the representation of the points on the factor map). An extra
column (named after sup_name) is added specifying whether an observation
is a supplementary point or not.
An object from which to get element(s) (a CA,
MCA or PCA object).
Currently not used.
A length-one numeric vector giving the subscript which the
data will be returned: 1 indicates individuals/rows (the default), 2
indicates variables/columns.
A character string specifying the name of the column to
create for supplementary points attribution (see below).
