msk.morphol.1998.aggregate {ecoval} | R Documentation |
Aggregation function of the highest node in the morphology module of the Swiss modular concept for stream assessment, level I (Regional survey) from 1998.
Description
Aggregates the values of the 2 sub-objectives at the highest aggregation level of the morphology module of the Swiss River Assessment Program MSK (1998). If the river is covered, the value for morphology is zero, otherwise it has the value of the uncovered node.
Usage
msk.morphol.1998.aggregate(u,
par = NA)
Arguments
u |
Numerical vector of length 2 containing the values that quantify the degree of fulfillment of the 2 sub-objettives. |
par |
Argument added for consistency with the other aggregation procedures. No parameters are needed. |
Value
The function returns the aggregated value.
