fitCoinertia {cocorresp}  R Documentation 
Performs a coinertia of the triplets (Q_1,K_1,R_0)
and
(Q_2,K_2,R_0)
.

n.axes 
number of axes to calculate the coinertia analysis for.

arguments passed to other functions. Currently ignored. 
A list with the following components:
U1 
column weights of 
U2 
column weights of 
X1 
rowscores of 
X2 
rowscores of 
lambda 
the Eigenvalues (squares of the singular values). 
n.axes 
number of axes requested. 
call 
the matched function call. 
This function is not yet meant to be called directly by the
user. If you wish to use it directly, see the function definition for
symcoca
which demonstrates how to prepare the
relevant input matrices.
Note that in this function, X
corresponds to the input
matrix y
and Y
corresponds to the
input matrix x
in symcoca
.
Confusing! This will be changed in a future release but for now the
arguments follow those of the original Matlab code  perhaps a little
too closely!
