ARMADA.heatmap {armada}R Documentation

Heatmap of the selected covariates.

Description

Heatmap of the selected covariates.

Usage

ARMADA.heatmap(X, Y, res.ARMADA.summary, threshold = 5)

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.

res.ARMADA.summary

the result of the function ARMADA, or output of the function ARMADA.summary.

threshold

an integer between 0 and 8: the selected covariates are those which have a score greater or equal to "threshold."

Details

This function plots the heatmap of the covariates which have a score higher than some threshold chosen by the user, with respect to the values of Y.

Value

the plot of the heatmap, and a data.frame of the selected covariables.
