Hi @KhalilBelghouat, glad to hear you find the package useful. Unfortunately, I'm unable to reproduce the error on my end. Could you also include your session info (e.g., sessionInfo()
)? I'm currently out on leave but will try to troubleshoot when I find time. (As a work around, you could always construct the plot manually from the output itself.)
Hi @bgreenwell, I hope you are doing well. I'm using R on a Google Colaboratory notebook, I guess this is perhaps the reason why the plot can't be displayed, but I'm not sure. I will go with the work around. Thanks for your help.

That might be the problem! Try upgrading the r kernel repl and see if that works:

Hi @bgreenwell, thanks for the guidance. Yesterday I used fastshap
to explain a caret model and worked fine, today I applied it again to the same model and got the error:
Error in UseMethod("explain"): no applicable method for 'explain' applied to an object of class "c('train', 'train.formula')"
What could be the reason for the error?
Edit 1:
I tried it on the lm
model provided as an example in the official documentation and isn't working either after working just fine yesterday.
Edit 2:
It actually worked after checking a post by someone who had the same issue: https://github.com/thomasp85/lime/issues/48
Most likely culprit is you loaded a package after fastshap that exports a function of the same name, in this case, explain(). Dplyr is the most common culprit for me. To see if that’s the issue, use fastshap::explain() instead of just explain(). If it works, then type ?explain in the console...if you get multiple options for a help page then that could tell you which one is the culprit.
You are absolutely right! I apologize for the bothering.
No apologies necessary! I wrote the package and still fall for the same error occasionally. Let this help you to always remember to try and manage your namespace and only import packages who’s functions you’ll rely on a bunch. I prefer to use pkgname::functionname() if I’m only using one or two functions and only a handful of times. This is one thing that’s a bit cleaner in Python.
Dear Brandon Greenwell,
I'm using the great 'fastshap' library to compute the approximate Shapley values, when running the first code example provided in the official CRAN document [1], the last line gives an error that states:
ERROR while rich displaying an object: Error in farver::decode_colour(colors, alpha = TRUE, to = "lab", na_value = "transparent"): unused argument (na_value = "transparent")
The code is:
