The description says to return 'null' in C#, 'None' in Rust, etc. It doesn't say anything about return types in R.

I think your point stands for the 'R' version though, because it is disproportionately difficult in R for an 8 Kyu kata - no beginner R programmer is going to think of the difference in return types between 'return(NULL)' and 'return(NA)'.

I agree with you that the R version really needs a hint to use an 'NA' return type.

LOL, translating it from a python solution doesplain why it isn't a very "R" way of doing things!

Please use a spoiler flag, comments are visible to everyone by default.

I agree it's very expensive at runtime.

This is supposed to be coding practice though. It's like if the task was to sort a vector and you used R's built-in sort() function. Yeah... that works, but then what's the point? This is supposed to be a 6 kyu exercise, meaning it should take more than using a built-in function to accomplish.

Fixed broken R kata with a fork.

I understand. I think there is a) not to reinvent the wheels, and b) write one's own code to show capability. Depending on the goals we may have different views, but I completely understand you.

This makes the problem trivial and is therefore not a good solution.

You can comment in the already open issue. Or try to fix the problem with a fork.

Yep, still an issue half a year later.

Duplicate issue.
