Inverse operation to enframe() #146

Would take a two-column data frame and produce a named vector or list.

Do we want this in tibble?

I recently had occasion to use exactly this, so 👍.

Specific use case within the tidyverse: if you have a tibble of factor levels and associated colours, ggplot2 really wants you to have this as a named vector of colours. I.e. to use in scale_color_manual().

Does the input have to be a two-column data frame? Or could it have more columns and deframe() (or whatever it's called) has a way to specify which variable you want and which one should become the names? If you only specify the primary variable, does this become the canonical way to get a single variable out of a tibble in a pipeline?

I'd prefer keeping things simple first (=only support one- or two-column data frames), we can extend later on.

Bug fixes

- Time series matrices (objects of class `mts` and `ts`) are now supported in `as_tibble()` (#184).
- The `all_equal()` function (called by `all.equal.tbl_df()`) now forwards to `dplyr` and fails with a helpful message if not installed. Data frames with list columns cannot be compared anymore, and differences in the declared class (`data.frame` vs. `tbl_df`) are ignored. The `all.equal.tbl_df()` method gives a warning and forwards to `NextMethod()` if `dplyr` is not installed; call `all.equal(, ...)` to avoid the warning. This ensures consistent behavior of this function, regardless if `dplyr` is loaded or not (#198).

Interface changes

- Now requiring R 3.1.0 instead of R 3.1.3 (#189).
- Add `as.tibble()` as an alias to `as_tibble()` (#160, @LaDilettante).
- New `frame_matrix()`, similar to `frame_data()` but for matrices (#140, #168, @LaDilettante).
- New `deframe()` as reverse operation to `enframe()` (#146, #214).
- Removed unused dependency on `assertthat`.



- Keep column classes when adding row to empty tibble (#171, #177, @LaDilettante).
- Singular and plural variants for error messages that mention a list of objects (#116, #138, @LaDilettante).
- `add_column()` can add columns of length 1 (#162, #164, @LaDilettante).

Input validation

- An attempt to read or update a missing column now throws a clearer warning (#199).
- An attempt to call `add_row()` for a grouped data frame results in a helpful error message (#179).


- Render Unicode multiplication sign as `x` if it cannot be represented in the current locale (#192, @ncarchedi).
- Backtick `NA` names in printing (#206, #207, @jennybc).
- `glimpse()` now uses `type_sum()` also for S3 objects (#185, #186, @holstius).
- The `max.print` option is ignored when printing a tibble (#194, #195, @t-kalinowski).


- Fix typo in `obj_sum` documentation (#193, @etiennebr).
- Reword documentation for `tribble()` (#191, @kwstat).
- Now explicitly stating minimum Rcpp version 0.12.3.


- Using registration of native routines.
