Calculates the base flow index of an object of class <code>'lfobj'</code>.

Base flow index

The "Manual on Low-flow Estimation and Prediction" (Gustard & Demuth (2009, ISBN:978-92-63-11029-9)), published by the World Meteorological Organisation, gives a comprehensive summary on how to analyse stream flow data focusing on low-flows. This packages provides functions to compute the described statistics and produces plots similar to the ones in the manual.

BFI function

<dl> <dt>lfobj</dt>
<dd>An object of class <code>'lfobj'</code></dd> <dt>year</dt>
<dd>The year for which the BFI should be computed. If <code>hyearstart != 1</code> the BFI is calculated for the hydrological, <code>year = "any"</code> means the whole series should be taken.</dd> <dt>breakdays</dt>
<dd>A vector of break days if the BFI should be calculated for different seasons.</dd> <dt>yearly</dt>
<dd>If TRUE, the BFI is calculated for each hydrological year separately.</dd></dl>
