common: A set of useful functions

Description

The common package is set of useful functions that enhance base R. These functions make up for some deficiencies in the base package. For example, there are functions to sort a data frame by multiple columns, and manipulate data frame labels. These are common activities, and can be used in almost any R program.

v: A generalized NSE quoting function.
sort.data.frame: An overload of the sort function for data frames.
labels.data.frame: An overload of the labels function for data frames.
