There was a problem hiding this comment.
Just wondering what is the reason why we add invisible in this PR? Is it related to this deprecation?

It's a R usability thing: for method not returning any value (in these cases the Scala method is defined as foo : Unit), it will print NULL.
so we say invisible to get it to not print out the value, that's all
so no, it's not really related to this deprecation - it's probably been around for quite a while
