A collection of functions for interpretation and presentation
of regression analysis.  These functions are used
to produce the statistics lectures in
http://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.".

Functions for Diffusing Function Documentations into 'Roxygen'
Comments
person(given = "Xiurui",
family = "Zhu",
role = c("aut", "cre"),
email = "zxr6@163.com",
comment = NULL)
Efficient diffusing of content across function documentations. Sections, parameters or dot parameters are extracted from function documentations and turned into valid Rd character strings, which are ready to diffuse into the 'roxygen' comments of another function by inserting inline code.

Work with Romanian Personal Numeric Codes PNC / CNP
person("Dragoș", "Moldovan-Grünfeld", , "dragos.mold@gmail.com",
role = c("aut", "cre", "cph"))
A set of tools for working with Romanian personal numeric codes.
The core is a validation function which applies several verification
criteria to assess the validity of numeric codes. This is accompanied by
functionality for extracting the different components of a personal numeric
code. A personal numeric code is issued to all Romanian residents either at
birth or when they obtain a residence permit.
