isNA

<p>Vector of string values to be considered as
missing. Defaults will match values that are equal to ., empty
string "", any number of white space elements, or charcter
string "N/A". We do not include "NA" by default because some
projects use "NA" to mean "not appropriate".</p>

na.strings

<p>A value vector in the key will generally be a character
vector.  This utility is used to check if the characters
are either R missing or values in a list of characters that
represent missings.</p>

Tools for data importation, recoding, and inspection that
are used at the University of Kansas Center for Research Methods
and Data Analysis. There are functions to create new project
folders, R code templates, create uniquely named output
directories, and to quickly obtain a visual summary for each
variable in a data frame.  The main feature here is the systematic
implementation of the "variable key" framework for data
importation and recoding.  We are eager to have community feedback
about the variable key and the vignette about it. In version 1.67,
the function semTable() is deprecated. We have proposed a new package
of that name.
