In SpaCCr: Spatial Convex Clustering

Description

Base function for computing SpaCC solution for single regularization value.

Usage

SpaCC(X, w, gamma, nu, verbose, tol, maxiter, Uinit, Vinit, Laminit)

Arguments

X	A subject (n) by probe (p) data matrix
w	A vector weights for adjacent probes. Should have length nprobes -1
gamma	A scalar value for the regularization parameter
nu	A scalar value for the step size in AMA algorithm
verbose	Logical value whether progress should be printed
tol	A scalar value for convergence tolerance.
maxiter	Maximum number of iterations
Uinit	A matrix used for warm starts with U
Vinit	A matrix used for warm start with V
Laminit	A matrix used for warm starts with Lam

Value

An RcppArmadillo field object. Has three components, each holds the U,V, and Lam matrix for the current regularization
