Hi @piotr-ole thanks for the message.
Indeed this should be joint entropy. Not sure how I put together the conditional 3 years ago when I made this commit 1378393
Feel free to provide a PR with the updated documentation if you like. If not, I can update that in a couple of days!

I think I have the very same mistake here https://github.com/MarcinKosinski/MarcinKosinski.github.io/blob/master/_source/2017-01-11-Entropy-Based-Image-Binarization.Rmd#L186

@MarcinKosinski An addition to this documentation discussion:
I think it could help to link the reference of Shannons entropy (Shannon 1984) to the help page.
Also currently it is now fully clear that H(X) expands into Shannons entropy as shown here.
I was asked to provide more references in a paper because the reviewer questioned the formula for information gain (and I assume he wanted to see Shannons Entropy in some sort).
