%description
Methods for detecting structural breaks, determining the number of breaks,
and estimating break locations in linear quantile regression, using one or
multiple quantiles, based on Qu (2008) and Oka and Qu (2011).  Applicable
to both time series and repeated cross-sectional data. The main function
is rq.break().
