Performs a coinertia of the triplets (Q_1,K_1,R_0) and (Q_2,K_2,R_0) with identity matrices K_1, K_2, R_0.
1  coinertiaI(X, Y, fast = TRUE)

X 
Species matrix X. 
Y 
Species Matrix Y. 
fast 
If 
Argument fast
is used to return only the row scores of
Y
in function permutest.coca
, which speeds the
permutation test considerably.
If fast = TRUE
, a matrix of row scores for matrix
Y
(see scores
below). If
fast = FALSE
a list with the following components:
weights 
A list with components 
scores 
A list with components 
lambda 
the Eigenvalues of the analysis (the square of the singular values from the SVD. 
call 
the matched function call. 
This function is not meant to be called directly by the user. If
you wish to use it study the code in
permutest.coca
to see how it should be called.
