r2dRue (version 1.0.4)

assessment: Performs the assessment component of a r2dRue analysis as specified by its associated parameters

Description

Computes Mean Observed RUE, Mean Observed Aridity, Extreme Observed RUE and Extreme Observed Aridity, and saves the results to corresponding raster files. A batch operation is parameterised from the r2dRue current memory settings (see read2dRfile and showInfo).

Rudimentary bars show the computation in progress.

Usage

assessment(o)

Arguments

o

A r2dRue Object

Value

The following raster files are created resulting from the assessment operation. They belong to the SpatialGridDataFrame class

rueObsMe

Mean Observed rain Use Efficiency

rueObsEx

Extreme Observed Rain Use Efficiency

aiObsMe

Mean Observed Aridity Index

aiObsEx

Extreme Observed Aridity Index

Details

The following r2dRue functions are involved in this computation. Local parameters are left with their respective default values, except those specified in the parameters file as displayed by showInfo:
