Clustering example does not work

[durraniu]

Thank you for this package. I have tried the example on the pkgdown site, but it throws an error as shown below:

Thanks for the report!

I'm surprised by that error message, because there is an S3 method for prep: https://github.com/tmastny/tsrecipes/blob/4151c4b1bc4543f18ca43e3fddc008eefe940bde/R/dtw.R#L62

I'll dive in and see what's going on tonight. Perhaps there was a breaking change in recipes.

I have experienced the same error. Is there any progress, concerning the issue?

Hi there, The same error occurs on the example and on another dataset. Is there any progress on this issue as it is still not working?
