If show="original", show="mean" or show="var", a numeric vector is returned which contains either the ratings obtained from the initial/original sequence, the average ratings across all randomizations, or the total variance.

If show="range" or show="all", a matrix is returned that contains either the range of ratings across all randomizations, or all ratings of all randomizations.

If you simply want to create the plot without any rating output being generated, use show=NULL.

ratings(x, "original", drawplot = FALSE)

# range of ratings across all randomizations
