coinertia {cocorresp}  R Documentation 
Performs a coinertia of the triplets (Q_1,K_1,R_0)
and
(Q_2,K_2,R_0)
.
coinertia(y, ...)
## Default S3 method:
coinertia(y, x, n.axes = NULL, weights = NULL,
symmetric = FALSE, ...)
y, x 
matrices or data frames of the two data sets for which axes of covariance are sought. 
n.axes 
numeric; the number of coinertia axes to retain. 
weights 
a vector of weights for the samples. If 
symmetric 
logical; should a symmetric set of weights be used. See Details. 
... 
arguments passed to other functions. Currently ignored. 
An object of class "coinertia"
, which is a list with the
following components:
scores 
a list of ordination scores, with components

weights 
numeric vector of row weights used in the analysis. 
lambda 
numeric vector of Eigenvalues. 
n.axes 
numeric; the number of coinertia axes extracted 
symmetric 
logical; was a symmetric analysis performed? 
call 
the matched call.
