nnTensor (version 1.3.0)

plotTensor2D: Plot function for visualization of matrix data structure

Description

Combined with recTensor function and the result of NTF or NTD, the reconstructed tensor structure can be visullized.

Usage

plotTensor2D(X = NULL, method=c("sd", "mad"),
    sign=c("positive", "negative", "both"), thr=2)

Arguments

X

Matrix object.

method

Cutoff method to focus on large/small value in the tensor data (Default: "sd").

sign

Direction to cutoff the large/small value in the tensor data (Default: "positive").

thr

Threshold of cutoff method (Default: 2).

Examples

tensordata <- toyModel(model = "CP")

out <- NTF(tensordata, rank=3, num.iter=2)

tmp <- tempdir()

png(filename=paste0(tmp, "/NTF.png"))
plotTensor2D(out$A[[1]])
