fp_add_scale

This function allows to add columns to a design matrix with scaled factor,
i.e. factors reported in real units rather in coded units (e.g. -1, 1).

A number of functions to create and analyze factorial plans according to the Design of Experiments (DoE) approach, with the addition of some utility function to perform some statistical analyses. DoE approach follows the approach in "Design and Analysis of Experiments" by Douglas C. Montgomery (2019, ISBN:978-1-119-49244-3). The package also provides utilities used in the course "Analysis of Data and Statistics" at the University of Trento, Italy.

fp_add_scale function

<dl><dt>dm</dt>
<dd>the design matrix to scale.</dd>
<dt>...</dt>
<dd>a set of factors to scale, with their respective ranges, e.g.
<code>A=c(10, 30), B=c(0, 1)</code>.if the range is not a two-number vector or the
factor is not numeric, a warning is printed and the factor is skipped.</dd>
<dt>suffix</dt>
<dd>the suffix to add to the scaled factor name in creating new
columns. If the suffix is the empty string, factors are replaced.</dd></dl>
