		From San Francisco to New York to Paris, city governments, high-class restaurants,
	schools, and religious groups are ditching bottled water in favor of what comes out of the
	faucet. With people no longer content to pay 1,000 times as much for bottled water, a
	product no better than water from the tap, a backlash against bottled water is growing.
(5)		The U.S. Conference of Mayors, which represents some 1,100 American cities,
	discussed at its June 2007 meeting the irony of purchasing bottled water for city employees
	and for city functions while at the same time touting1 the quality of municipal water. The
	group passed a resolution sponsored by Mayors Gavin Newsom of San Francisco, Rocky
	Anderson of Salt Lake City, and R. T. Rybak of Minneapolis that called for the examination
(10)	of bottled water’s environmental impact. The resolution noted that with $43 billion a year

#' Convert a list of vectors to a data frame.

#' of columns equal to the number of unique names across all vectors. In cases
#' where some vectors do not have names in other vectors, those values will be
#' filled with \code{NA}.
#' 
#' The second case is when all the vectors are of the same length. In this case,
