Dual STATIS
DSTATIS(Data, Group, ncomp = NULL, Scale = FALSE, graph = FALSE)
a numeric matrix or data frame
a vector of factors associated with group structure
number of components, if NULL number of components is equal to 2
scaling variables, by defalt is False. By default data are centered within groups.

list with the following results:
original data
Concatenated centered data
Group centered data
Group as a factor vector
The RV coefficient matrix
Vector of weights
Compromise variance-covariance matrix
Matrix of common loadings
