dieft {dief}

R Documentation

Compute metric dief@t

Description

This function computes the dief@t metric at a point in time t.

Usage

dieft(inputtrace, inputtest, t = -1)

Arguments

inputtrace	dataframe with the answer trace. Attributes of the dataframe: test, approach, answer, time.
inputtest	string that specifies the specific test to analyze from the answer trace.
t	point in time to compute dieft. By default, the function computes the minimum of the execution time among the approaches in the answer trace.

Examples

# Compute dief@t when t is the time where the slowest approach produced the last answer.
dieft(traces, "Q9.sparql")
# Compute dief@t after 7.5 time units (seconds) of execution. 
dieft(traces, "Q9.sparql", 7.5)
