Provide rbind method

[hadley]

That uses dplyr::bind_rows().

Moved from tidyverse/dplyr#1385

[krlmlr]

Does this mean copying the bind_rows() implementation from dplyr? This seems to need at least Collecter, SlicingIndex and set_rownames().

[hadley]

Yeah, I'm not sure how to deal with that. One option would be to add a dplyr dependency to tibble (just a suggest), but that seems suboptimal.

[krlmlr]

I think I'll add rbind.tbl_df() and make sure it behaves like the dplyr equivalent.

[hadley]

I think we can leave this for now.

[gavinsimpson]

Can this be reconsidered/reopened? Part of the justification for tibble is so you don't need all of dplyr just to have the data frame goodness. As such tibble should provide a suite of tools for working with tibbles or tbl_dfs.

An rbind.tbl_df() would be a most useful addition to this package

[hadley]

Not in near future - there is a lot of code powering bind rows that we'd need to duplicate. All the variable coercion stuff is complicated.

[gavinsimpson]

Is it being considered for the longer term future? Closing this issue gave me the impression this wasn't something you were going to deal with.

I have no doubt this is complicated; if it were easy I suspect it would have been done by now.

[hadley]

In the long long term I'd like to move data frame stuff related here but it's probably at least a year away

[krlmlr]

I think we could do just what data.table does -- they're patching rbind.data.frame(): tidyverse/dplyr#606 (comment).
