@OfekShilon Many thanks. I invited you to be project member so amongst other things you can create branches in main repo in future. The invite is a button in your profile or projects page in github that you have to click to accept. Thanks again and welcome! |

There were no unit test for the second closed issue so I added them in follow up PR #4985 |

@mattdowle Thank you very much, I'll do my best to contribute. If I understand correctly - I'm not allowed to merge PRs, right? Also, what is the right place to ask such questions? (probably not in a PR comments) |

Just me (and Arun) who can merge currently, but that may expand to Jan and Michael in future. |

This is failing R 3.1.0 with :
> af[, mean(a), by = "itime"]
Error in .Primitive("as.character")(list, ...) :
cannot coerce type 'builtin' to vector of type 'character'
Calls: [ -> [.data.table -> rapply
Execution halted
will fix ...

Closes #4981
There are at least 2 other places in
[.data.tablethat test for inclusion ofgetet.al. in an expression - I think they should use rapply too, but didn't touch it.
