Magic functions to obtain results from for loops.

Bindings to 'ImageMagick': the most comprehensive open-source image
    processing library available. Supports many common formats (png, jpeg, tiff,
    pdf, etc) and manipulations (rotate, scale, crop, trim, flip, blur, etc).
    All operations are vectorized via the Magick++ STL meaning they operate either
    on a single frame or a series of frames for working with layers, collages,
    or animation. In RStudio images are automatically previewed when printed to
    the console, resulting in an interactive editing environment. Also includes
    a graphics device for creating drawing onto images using pixel coordinates.

Enables us to use the functions of the package 'magick' interactively.

Set of utility functions to interact with 'WeMo Switch', a smart 
    plug that can be remotely controlled via wifi. The provided functions make 
    it possible to turn one or more 'WeMo Switch' plugs on and off in a 
    scriptable fashion. More information about 'WeMo Switch' can be found at

Constructs a magic rectangle or a nearly magic rectangle of
    order p x q for every order for which one exists, together with
    existence classification and verification utilities. A magic rectangle
    arranges the integers 1 to p*q so that all row sums are equal and all
    column sums are equal; it exists exactly when p and q have the same
    parity, excluding 2 x 2 and degenerate single-row/column cases
    (Hagedorn, 1999, <doi:10.1016/S0012-365X(99)00041-2>). When p and q have
    opposite parity a nearly magic rectangle exists instead, with constant
    sums along one direction and sums differing by at most one along the
    other (Chai, Singh and Stufken, 2019, Journal of Combinatorial Designs
    27(6), 368-376).
    Implements the constructions of De Los Reyes, Das, Midha and Vellaisamy
    (2009) for even by even orders, Chai, Das and Midha (2013) for odd by
    odd orders, and Chai, Singh and Stufken (2019) for the nearly magic
    (even by odd) case.
