jbryer / parse.codebook.r
Last active Nov 3, 2016
Parses a codebook file where lines starting at column zero (far left) represet variable information (e.g. name, description, type) and indented lines (i.e. lines beginning with white space, either tabs or spaces, etc.) represent factor levels and labels.

Returns the quarter in which the date appears.
View getYearQuarter.R
#' Returns the year (fiscal or calendar) and quarter in which the date appears.

#' This function will cut the given date vector into quarters (i.e. three month
#' increments) and return an ordered factor with levels defined to be the quarters
#' between the minimum and maximum dates in the given vector. The levels, by
#' default, will be formated as \code{FY2013-Q1}, however the \code{FY} and \code{Q}
#' can be changed using the \code{fy.prefix} and \code{quarter.prefix} parameters,

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
