Should the names of the variables be returned? Or the column indices? Defaults to FALSE 
(meaning the column indices will be returned).

names

Given a starting string and an ending string, <code>r</code> will extract all columns between the first 
and the last string and return either a vector of strings or a vector of integers.
See examples.

Functions and datasets that can be used for data cleanup (e.g., functions for eliminating all but a few columns from a dataset, selecting a range of columns, quickly editing column names), plotting/presenting data (prism-like reproductions, spearman plots for ordinal data, making colored tables, plotting interactions with quantitative variables), and analyses common to biostatistics (e.g., random forest, multiple comparisons with chi square tests). See the package vignette for a brief introduction to many of the main functions.
