After "Summary Kendall's tau" in section 2.2, two warnings are shown when using the data set from the package (data_matrix.csv).
This is due to the fact that missing values cannot be plotted:
Summary Kendall's tau
| Task | mean | median | q25 | q75 |
| c_ideal | 1.0 | 1.0 | 1.0 | 1.0 |
| c_random | 1.54 | 0.6 | 0.4 | 0.8 |
| c_worstcase | NaN | Na | Na | NA |
How should we deal with it? Should we use the treat.na argument, directly remove it or remove the warning from the plot?
it's not because of missing test cases. It is because in certain situation no Kendall can be computed. Don't use treat.na for this.
Yes, this results in Na, but they shouldn't be treated like before; you're right. @wiesenfa: What do you propose for the plots? Should we just remove the warnings?
