This package has been primarily developed\nfor assessing the quality of daily streamflow time series. It\nalso contains tools for plotting and calculating many different\nstreamflow metrics. The package can be used to produce summary\nscreening plots showing change-points and significant temporal\ntrends for high flow, low flow, and/or baseflow statistics, or\nit can be used to perform more detailed hydrological time\nseries analyses. The package was designed for screening daily\nstreamflow time series from Water Survey Canada and the United\nStates Geological Survey but will also work with streamflow\ntime series from many other agencies. Package update to version\n2.0 made updates to read.flows function to allow loading of\nGRDC and ROBIN streamflow record formats. This package uses the\n`changepoint` package for change point detection.
