plot.pdsi

an object of class <code>pdsi</code>.

determines PDSI, PHDI (Palmer hydrological drought index)
or WPLM (weighted PDSI) to be plotted. Default "PDSI".

index

additional parameters, not used at present.

plot the timeseries of calculated (sc)PDSI.

Calculating the monthly conventional and self-calibrating Palmer
Drought Severity Index (PDSI and scPDSI) using the precipitation and potential
evapotranspiration data. The function to calculate PDSI is based on the C++
source codes developed by Nathan Wells, Steve Goddard and Michael J. Hayes,
University of Nebraska-Lincoln.
