Fastshap with tree augmented naive bayes of caret (tan)

Gotcha @PARODBE, and thanks for the link. If you’d be kind enough to post a small reproducible example, I’d be happy to take a look!!

Fastshap with tree augmented naive bayes of caret (tan)

Hi @PARODBE, I have not found the time yet, but if you have a [reprex](https://reprex.tidyverse.org/) I could run on my end, it would make it a lot easier to narrow...

X (explain object) is a list

Hi @frahsimon, thank you for your interest in the package. Do you have a small reproducible example I can work with to help put this into context?

~4000 0bservations-- tibble giving one row of outputs

Hi @jg3405, in order to help, I’d need to see a reproducible example. Can you try posting one here?

~4000 0bservations-- tibble giving one row of outputs

Thanks for the example code @jg3405. The issue is that your prediction wrapper is returning probability estimates for both classes, but `explain()` can only work with one predicted output. All...

~4000 0bservations-- tibble giving one row of outputs

I'll try to add an informative error message for this in the next release!

~4000 0bservations-- tibble giving one row of outputs

Hi @trilliumtechnical, it is difficult to provide a good answer without a reproducible example, but in general, the reference class for the Shapley values is dictated by the probability estimates...

~4000 0bservations-- tibble giving one row of outputs

@trilliumtechnical thanks for including an example. I see two issues with your code: 1. `pfunWF()` does not return anything (so simply omit the `y
