reorder_columns

Reorders columns according to a prefered target order

Provides some low-level utilities to use for package
development. It currently provides managers for multiple package specific
options and registries, vignette, unit test and bibtex related utilities.
It serves as a base package for packages like 'NMF', 'RcppOctave', 'doRNG', and
as an incubator package for other general purposes utilities, that will
eventually be packaged separately.
It is still under heavy development and changes in the interface(s) are
more than likely to happen.

reorder_columns function

<dl><dt>x</dt>
<dd>an object with columns, such as a <code>matrix</code> or a <code>data.frame</code>,
or from a class that support subsetting via <code>x[, i, drop = FALSE]</code> and has a method <code>colnames</code>.</dd>
<dt>target</dt>
<dd>a character or named numeric vector that specifies the column prefered order.
If a numeric vector, then its names are assumed to correspond to columns,
and its values determine the target order -- according to argument <code>decreasing</code>.</dd>
<dt>decreasing</dt>
<dd>logical that indicates in which direction a numeric target vector should
be ordered.</dd></dl>
