Description

Scores of all the covariates present in X, given the vector Y of the response.

Usage

2
ARMADA(X, Y, nclust = NULL, clusterType = c("PSOCK", "FORK"),
  parallel = FALSE)

Arguments

X

the matrix (or data.frame) of covariates, dimension n*p (n is the sample size, p the number of covariates). X must have rownames, which are the names of the n subjects (i.e. the user ID of the n subjects). X must have colnames, which are the names of the p covariates.

Y

the vector of the response, length n.

nclust

the number of clusters in the covariates dataset X.

clusterType

to precise the type of cluster of the machine. Possible choices: "PSOCK", or "FORK" (for UNIX or MAC systems, but not for WINDOWS).

parallel

= TRUE if the calculus are made in parallel (default choice is FALSE).

Value

a 3-list with: "tree" which is the dendrogram of the data X, "nclust" which is a proposition of the number of clusters in the data X, "result" which is a data.frame with p rows and 2 columns, the first column gives the names of the covariates, the second column is the scores of the covariates.
