scale_med

Centers and scales the columns of a matrix robustly

Supports fMRI (functional magnetic resonance imaging)
analysis tasks including reading in 'CIFTI', 'GIFTI' and
'NIFTI' data, temporal filtering, nuisance regression, and
aCompCor (anatomical Components Correction) (Muschelli et al.
(2014) <doi:10.1016/j.neuroimage.2014.03.028>).

scale_med function

<dl><dt>mat</dt>
<dd>A numeric matrix. Its columns will be centered and scaled.</dd>
<dt>TOL</dt>
<dd>Columns with MAD below this value will be considered constant.
Default: <code>1e-8</code></dd>
<dt>drop_const</dt>
<dd>Drop constant columns? Default: <code>TRUE</code>. If
<code>FALSE</code>, set to <code>NA</code> instead.</dd>
<dt>doRows</dt>
<dd>Center and scale the rows instead? Default: <code>FALSE</code>.</dd></dl>
