direction parameter in the cutpointr() about cutpointr HOT 2 CLOSED

Hi Jiang,

unfortunately, I have only implemented >= and <=.

The difference between > and >= matters only with few unique values (as in the example suicide dataset) and if use_midpoints = FALSE.

For that reason and because this feature was not requested thus far, I have not implemented it and also do not plan to do so – unless there is a good argument why it is needed. You are mainly interested in comparing the results to a different tool, right?

So you can unfortunately not set direction = ">", but you could try setting use_midpoints = TRUE which should bring the optimal cutpoint closer to the one that would be obtained with direction = ">" and use_midpoints = FALSE.

(I think with use_midpoints = TRUE the optimal cutpoint would actually be identical with > and >=)

Best,
Christian
