Description

Compare similarity scores for two songs

Usage

compareScores(scof, song1flag = "tutor", c1s1, c2s1, plotdiff = F)

Arguments

scof	Score file addresses for the two comparisons. The order of the comparisons, 1 or 2, does not matter here. Value must be vector of two character strings.
song1flag	Flag in the name of each score file that marks the
c1s1	Identifier of song 1 in comparison 1.
c2s1	Identifier of song 1 in scof2. identifier of song 1.
plotdiff	Logical. Should the score differences be plotted?

Details

This function calculates the difference in similarity scores for two songs, asumming that in each comparison the second songis the same. The function reads the scores calculated over each spectral window of song 2 and substracts the score in the second comparison from the score in the first comparison.

Song 1 in each comparison must have a unique identifier expressed as a character string. The identifier needs to be unique only between the two score files loaded into the function. The identifier should be present in the name of the score file and marked by a flag, which must also be specified by the user. The format of the flag and the identifier is as follows:

_<flag>-<identifier><underscore or file extension>

In the following example the identifiers are "father" and "neighbor" and the flag is "tutor". They are written into the filenames in this way:

comparison1_tutor-father.sco

comparison2_tutor-neighbor.sco

Because a file may contain multiple flags, the user must specify the flag, and the identifiers, when calling the function.

Normalized mutual information matrices (nmi file) must be in the same folder as the score file. All score files must have their respective accompanying nmi file.
