diefk2 {dief}R Documentation

Compute dief@k at a portion of the answer

Description

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

Usage

diefk2(inputtrace, inputtest, kp = -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.

kp

portion of answers to compute diefk (between 0.0 and 1.0). By default and when kp=1.0, this function behaves the same as diefk. It computes the kp portion of of minimum of of number of answers produced by the approaches.
