diefk: Compute metric dief@k

In farahkarim/dief-2: Metrics for Continuous Efficiency

Description

This function computes the dief@k metric at a given k (number of answers).

Usage

diefk(inputtrace, inputtest, k = -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.
k	number of answers to compute diefk. By default, the function computes the minimum of the total number of answers produced by the approaches.
