bfi {baseflow} | R Documentation |
Function provided by package baseflow
to compute baseflow index from a BaseflowFilter
object.
bfi(filter)
filter |
A |
Computes baseflow index from a BaseflowFilter
object, created by BaseflowFilter
function. If the baseflow values have not been computed yet in the object, a Rust routine is called to compute baseflow ; else, baseflow is computed directly from baseflow and observed streamflow values. Providing a non-BaseflowFilter
object creates an error.
A numeric giving computed baseflow index.
