DetermineDFromIRLBA {jrSiCKLSNMF}

Create elbow plots of the singular values derived from IRLBA to determine D for large datasets

Description

This generates v+1 plots, where v is the number of data modalities, of the approximate singular values generated by IRLBA.There is one plot for each modality and then a final plot that concatenates all of the modalities together. Choose the largest elbow value among the three plots.

Usage

DetermineDFromIRLBA(SickleJr, d = 50)

Arguments

SickleJr

An object of class SickleJr

d

Number of desired factors; it is important to select a number that allows you to see a clear elbow: defaults to 50.

Value

An object of class SickleJr with plots for IRLBA diagnostics added to its plots slot
