summarizeNumerics

If TRUE (default), the columns are re-organized
in alphabetical order. If FALSE, they are presented in the
original order.

alphaSort

If TRUE (default), include mean, standard deviation, and count of NAs.

sumstat

integer, used for number formatting output.

digits

This function finds the numeric variables and ignores the
others. (See <code>summarizeFactors</code> for a function that
handles non-numeric variables.). It calculates the quantiles for
each variable, as well as the mean, standard deviation, and
variance, and then packs those results into a matrix. The main
benefits from this compared to R's default summary are 1) more
summary information is returned for each variable (dispersion), 2)
the results are returned in a matrix that is easy to use in
further analysis, 3) the columns in the output are
alphabetized. To prevent alphabetization, use
alphaSort = FALSE.

A collection of functions for ease of
    presentation and interpretation of regression analysis.
    These functions are used to produce the statistics lectures
    in http://pj.freefaculty.org/guides. There
    are functions to explore the effect (or lack thereof) from
    "mean centering," "residual centering", and standardization.
    The vignette "rockchalk" offers a fairly comprehensive overview.
    The vignette "Rstyle" has advice about coding in R.
    See the outreg function for a convenient way to generate
    regression models for reports. For nice, easy to use pictures,
    see plotSlopes, plotCurves, plotPlane.
    The package title "rockchalk" refers to our school motto,
    "Rock Chalk Jayhawk, Go K.U.".

summarizeNumerics: Extracts numeric variables and presents an alphabetized summary in a workable format.
