scale_protti

<code>scale_protti</code> is used to scale a numeric vector either between 0 and 1 or around a
centered value using the standard deviation. If a vector containing only one value or
repeatedly the same value is provided, 1 is returned as the scaled value for <code>method = "01"</code>
and 0 is returned for <code>metod = "center"</code>.

Useful functions and workflows for proteomics quality control and data analysis of both limited proteolysis-coupled mass spectrometry (LiP-MS) (Feng et. al. (2014) <doi:10.1038/nbt.2999>) and regular bottom-up proteomics experiments. Data generated with search tools such as 'Spectronaut', 'MaxQuant' and 'Proteome Discover' can be easily used due to flexibility of functions.

scale_protti function

<dl><dt>x</dt>
<dd>a numeric vector</dd>
<dt>method</dt>
<dd>a character value that specifies the method to be used for scaling. "01" scales
the vector between 0 and 1. "center" scales the vector equal to <code><a href="/link/base%3A%3Ascale?package=protti&version=0.9.0" data-mini-rdoc="protti::base::scale">base::scale</a></code> around a
center. This is done by subtracting the mean from every value and then deviding them by the
standard deviation.</dd></dl>

Arguments

Scaling a vector — scale_protti

<dl>

<dt>x</dt>
<dd>a numeric vector</dd>


<dt>method</dt>
<dd>a character value that specifies the method to be used for scaling. "01" scales
the vector between 0 and 1. "center" scales the vector equal to <code><a href='https://rdrr.io/r/base/scale.html'>base::scale</a></code> around a
center. This is done by subtracting the mean from every value and then deviding them by the
standard deviation.</dd>
