is.empty

<code>array</code>, <code>matrix</code> or <code>vector</code> of any type.

Internal subroutine called by end-user <code><a href="/link/mvr?package=MVR&version=1.00.0&to=MVR" rd-options="MVR" data-mini-rdoc="MVR::mvr">mvr</a></code> and <code><a href="/link/mvrt.test?package=MVR&version=1.00.0&to=MVR" rd-options="MVR" data-mini-rdoc="MVR::mvrt.test">mvrt.test</a></code> functions to represent the empty 
    array, matrix, or vector of zero dimension or length. Often returned by expressions and functions whose value is undefined.

MVR is a non-parametric method for joint adaptive
        mean-variance regularization and variance stabilization of
        high-dimensional data. It is suited for handling difficult
        problems posed by high-dimensional multivariate datasets (p >>
        n paradigm), such as in omics-type data, among which are that
        the variance is often a function of the mean, variable-specific
        estimators of variances are not reliable, and tests statistics
        have low powers due to a lack of degrees of freedom. Key
        features include (i) Normalization and/or variance
        stabilization of the data, (ii) Computation of
        mean-variance-regularized t- and F-statistics, (iii) Generation
        of diverse diagnostic plots, (iv) Computationally efficiency
        implementation, using C++ interfacing, and an option for
        parallel computing to enjoy a fast and easy experience in the R
        environment.
