Error in dst_get_data()

[Frederik Hjorth]

This is a terrifically useful package! Unfortunately, I get an error message "object of type 'closure' is not subsettable" when running dst_get_data(), even when running exactly the examples in the Readme file. It shows up both in Windows and OSX. Am I missing something obvious?

I'll check it out some time this weekend. Can I get your sessionInfo()?

Thanks a lot! sessionInfo() here:

FWIW, it may be that the code tries to index a function somewhere, cf. http://stackoverflow.com/a/11308796

I've tried to work through dst_get_data() step by step. It looks like the bug is in the dst_query_match() helper function.

[Kenneth Rose]

I just pushed a new version. I couldn't reproduce your error because I had already fixed the function dst_query_match locally but had forgotten to commit and push the changes.

I tried to subset on dst_meta (the function) instead of the meta_data. Sorry about the problems you were having. I hope it works now.

[Frederik Hjorth]

Yes, it works now! Thanks for looking into this so quickly. And I'm just happy to contribute in my small way 😄
