magRange

By default, R's range function returns the minimum and maximum
values of a variable. This returns a magnified range. It is used
for some plotting functions in the rockchalk package

A collection of functions for interpretation and presentation
of regression analysis. These functions are used
to produce the statistics lectures in
<https://pj.freefaculty.org/guides/>. Includes regression
diagnostics, regression tables, and plots of interactions and
"moderator" variables. The emphasis is on "mean-centered" and
"residual-centered" predictors. The vignette 'rockchalk' offers a
fairly comprehensive overview. The vignette 'Rstyle' has advice
about coding in R. The package title 'rockchalk' refers to our
school motto, 'Rock Chalk Jayhawk, Go K.U.'.

magRange function

<dl><dt>x</dt>
<dd>an R vector variable</dd>
<dt>mult</dt>
<dd>a multiplier by which to magnify the range of the
variable. A value of 1 leaves the range unchanged. May be a
scalar, in which case both ends of the range are magnified by the
same amount. May also be a two valued vector, such as c(minMag,
maxMag), in which case the magnification applied to the minimum is
minMag and the magnification of the maximum is maxMag. After
version 1.5.5, mult may be smaller than 1, thus shrinking the
range. Setting mult to values closer to 0 causes the range to
shrink to the center point from both sides.</dd></dl>
