Three dots are used even for "unique"
name repair (#566).
add_row()
, add_case()
and add_column()
now signal a warning once per session if the input is not a data frame (#575).
Fix view()
for the case when an object named x
exists in the global environment (#579).
tibble names can again be set to NULL
within RStudio, as some R routines within RStudio relied on this behaviour (#563, @kevinushey).
as_tibble.matrix(validate = TRUE)
works again, with a lifecycle warning (#558).
Replace new_list_along()
by rep_along()
to support rlang 0.3.1 (#557, @lionel-).
The tibble()
and as_tibble()
functions, and the low-level new_tibble()
constructor, have undergone a major overhaul to improve consistency. We suspect that package code will be affected more than analysis code.
To improve compatibility with existing code, breaking changes were reduced to a minimum and in some cases replaced with a warning that appears once per session. Call tibble:::scoped_lifecycle_errors()
when updating your packages or scripts to the new semantics API to turn these warnings into errors. The compatibility code will be removed in tibble 3.0.0.
All optional arguments have moved past the ellipsis, and must be specified as named arguments. This affects mostly the n
argument to as_tibble.table()
, passing n
unnamed still works (with a warning).
new_tibble()
has been optimized for performance, the function no longer strips dimensions from 1d arrays and no longer checks correctness of names or column lengths. (It still checks if the object is named, except for zero-length input.) Use the new validate_tibble()
if you need these checks (#471).
The nrow
argument to new_tibble()
is now mandatory. The class
argument replaces the now deprecated subclass
argument, the latter will be supported quietly for some time (#518).
Setting names on a tibble via names(df) <- ...
now also requires minimal names, otherwise a warning is issued once per session (#466).
In as_tibble()
, checking names is also enabled by default, even for tibbles, matrices and other matrix-like objects: names must exist, NA
names are not allowed. Coercing a matrix without column names will trigger a warning once per session. (This corresponds to the "minimal"
checks described below.).
The validate
argument to as_tibble()
has been deprecated, see below for alternatives. (The as_tibble.tbl_df()
method has been removed, the as_tibble.data.frame()
method will be used for tibbles.)
as_tibble()
always checks that all columns are 1D or 2D vectors and not of type POSIXlt
, even with validate = FALSE
(which is now deprecated).
Calling as_tibble()
on a vector now warns once per session. Use enframe(name = NULL)
for converting a vector to a one-column tibble, or enframe()
for converting a named vector to a two-column tibble.
data_frame()
and frame_data()
are soft-deprecated, please use tibble()
or tribble()
(#111).
tibble_()
, data_frame_()
, and lst_()
are soft-deprecated. Please use tibble()
or lst()
(#111, #509).
as.tibble()
and as_data_frame()
are officially deprecated and not generic anymore, please use/implement as_tibble()
(#111).
as_tibble.data.frame()
(and also as_tibble.matrix()
) strip row names by default. Code that relies on tibbles keeping row names now will see:
rownames()
or row.names()
,NA
values when subsetting rows with with a character vector, e.g. as_tibble(mtcars)["Mazda RX4", ]
.Call pkgconfig::set_config("tibble::rownames", NA)
to revert to the old behavior of keeping row names. Packages that import tibble can call set_config()
in their .onLoad()
function (#114).
as_tibble()
drops extra classes, in particular as_tibble.grouped_df()
now removes grouping (#535).
column_to_rownames()
now always coerces to a data frame, because row names are no longer supported in tibbles (#114).
In all *_rownames()
functions, the first argument has been renamed to .data
for consistency (#412).
Subsetting one row with [..., , drop = TRUE]
returns a tibble (#442).
The print.tbl_df()
method has been removed, the print.tbl()
method handles printing (#519).
tibble()
supports columns that are matrices or data frames (#416).
The new .rows
argument to tibble()
and as_tibble()
allows specifying the expected number of rows explicitly, even if it’s evident from the data. This allows writing more defensive code.
Column name repair has more direct support, via the new .name_repair
argument to tibble()
and as_tibble()
. It takes the following values:
"minimal"
: No name repair or checks, beyond basic existence."unique"
: Make sure names are unique and not empty."check_unique"
: (default value), no name repair, but check they are unique
."universal"
: Make the names unique
and syntactic..name_repair = make.names
or .name_repair = ~make.names(., unique = TRUE)
for names in the style of base R).The validate
argument of as_tibble()
is deprecated but supported (emits a message once per session). Use .name_repair = "minimal"
instead of validate = FALSE
, and .name_repair = "check_unique"
instead of validate = TRUE
. If you need to support older versions of tibble, pass both .name_repair
and validate
arguments in a consistent way, no message will be emitted in this case (#469, @jennybc).
Row name handling is stricter. Row names are never (and never were) supported in tibble()
and new_tibble()
, and are now stripped by default in as_tibble()
. The rownames
argument to as_tibble()
supports:
NULL
: remove row names (default),NA
: keep row names,The old default can be restored by calling pkgconfig::set_config("tibble::rownames", NA)
, this also works for packages that import tibble.
new_tibble()
and as_tibble()
now also strip the "dim"
attribute from columns that are one-dimensional arrays. (tibble()
already did this before.)
Internally, all as_tibble()
implementation forward all extra arguments and ...
to as_tibble.list()
where they are handled. This means that the common .rows
and .name_repair
can be used for all inputs. We suggest that your implementations of this method do the same.
enframe()
(with name = NULL
) and deframe()
now support one-column tibbles (#449).
Improved S4 support by adding exportClass(tbl_df)
to NAMESPACE
(#436, @jeffreyhanson and @javierfajnolla).
New validate_tibble()
checks a tibble for internal consistency (#471).
Bring error message for invalid column type in line with allowed matrix/df cols (#465, @maxheld83).
view()
function that always returns its input invisibly and calls utils::View()
only in interactive mode (#373).The set_tidy_names()
and tidy_names()
helpers the list of new names using a bullet list with at most six items (#406).
A one-character ellipse (cli::symbol$ellipsis
) is printed instead of "..."
where available, this affects glimpse()
output and truncated lists (#403).
Column names and types are now formatted identically with glimpse()
and print.tbl_df()
.
tidy_names()
quotes variable names when reporting on repair (#407).
All error messages now follow the tidyverse style guide (#223).
as_tibble()
prints an informative error message when using the rownames
argument and the input data frame or matrix does not have row names (#388, @anhqle).
column_to_rownames()
uses the real variable name in its error message (#399, @alexwhan).
Lazy tibbles with exactly 10 rows no longer show “…with more rows” (#371).
glimpse()
shows information obtained from tbl_sum()
, e.g. grouping information for grouped_df
from dplyr (#550).
glimpse()
takes coloring into account when computing column width, the output is no longer truncated prematurely when coloring is enabled.
glimpse()
disambiguates outputs for factors if the levels contain commas (#384, @anhqle).
print.tbl_df()
with a negative value for n
behaves as if n
was omitted (#371).
Use fansi::strwrap_ctl()
instead of own string wrapping routine.
tibble()
uses recycled values during construction but unrecycled values for validation.
tibble()
is now faster for very wide tibbles.
Avoid use of stop()
in examples if packages are not installed (#453, @Enchufa2).
Fix as_tibble()
examples by using correct argument names in requireNamespace()
call (#424, @michaelweylandt).
as_tibble()
checks column length only once (#365, @anhqle).
Using rlang::list2()
(#391, @lionel-).
enframe(NULL)
now returns the same as enframe(logical())
(#352).tribble()
now ignores trailing commas (#342, @anhqle).The new pillar package is now responsible for formatting tibbles. Pillar will try to display as many columns as possible, if necessary truncating or shortening the output. Colored output highlights important information and guides the eye. The vignette in the tibble package describes how to adapt custom data types for optimal display in a tibble.
add_case()
an alias for add_row()
(#324, @LaDilettante).as_tibble()
gains rownames
argument (#288, #289).as_tibble.matrix()
repairs column names.`[.tbl_df`()
supports drop = TRUE
and omits the warning if j
is passed. The calls df[i, j, drop = TRUE]
and df[j, drop = TRUE]
are now compatible with data frames again (#307, #311).glimpse()
(#328).add_column()
from dropping classes and attributes by removing the use of cbind()
. Additionally this ensures that add_column()
can be used with grouped data frames (#303, @DavisVaughan).add_column()
to an empty zero-row tibble with a variable of nonzero length now produces a correct error message (#319).has_name()
from rlang, instead of forwarding, to avoid warning when importing both rlang and tibble.tibble()
call are recycled prior to evaluating subsequent arguments, improving consistency with mutate()
(#213).tibble()
call maintains their class (#284).add_row()
now always preserves the column data types of the input data frame the same way as rbind()
does (#296).lst()
now again handles duplicate names, the value defined last is used in case of a clash.validate
argument is now also supported in as_tibble.tbl_df()
, with default to FALSE
(#278). It must be passed as named argument, as in as_tibble(validate = TRUE)
.format_v()
now always surrounds lists with []
brackets, even if their length is one. This affects glimpse()
output for list columns (#106).glimpse()
(#280).tibble()
gives a consistent error message in the case of duplicate column names (#291).format()
and print()
methods for both tbl
and tbl_df
classes, to protect against malformed tibbles that inherit from "tbl_df"
but not "tbl"
, as created e.g. by ungroup()
in dplyr 0.5.0 and earlier (#256, #263).tidy_names(syntactic = TRUE, quiet = FALSE)
if not all names are fixed (#260, @imanuelcostigan).set_tidy_names()
and tidy_names()
, a simpler version of repair_names()
which works unchanged for now (#217).rowid_to_column()
that adds a rowid
column as first column and removes row names (#243, @barnettjacob).all.equal.tbl_df()
method has been removed, calling all.equal()
now forwards to base::all.equal.data.frame()
. To compare tibbles ignoring row and column order, please use dplyr::all_equal()
(#247).x
again instead of the Unicode multiplication sign, to avoid encoding issues (#216).print()
, format()
, and tbl_sum()
methods are now implemented for class "tbl"
and not for "tbl_df"
. This allows subclasses to use tibble’s formatting facilities. The formatting of the header can be tweaked by implementing tbl_sum()
for the subclass, which is expected to return a named character vector. The print.tbl_df()
method is still implemented for compatibility with downstream packages, but only calls NextMethod()
.print.data.frame()
anymore. Now providing format.tbl_df()
and full support for Unicode characters in names and data, also for glimpse()
(#235).rlang

(#184).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(as.data.frame(...), ...)
to avoid the warning. This ensures consistent behavior of this function, regardless if dplyr
is loaded or not (#198).as.tibble()
as an alias to as_tibble()
(#160, @LaDilettante).frame_matrix()

(hadley/dplyr#1325). The default width is obtained from the tibble.width
option (#35, #56).as_data_frame()
is now an S3 generic with methods for lists (the old as_data_frame()
), data frames (trivial), matrices (with efficient C++ implementation) (hadley/dplyr#876), and NULL
(returns a 0-row 0-column data frame) (#17, @jennybc).frame_data()

falls back to regular subsetting when used with anything other than a single string (#29). base::getElement()
now works with tibbles (#9).all_equal()
allows to compare data frames ignoring row and column order, and optionally ignoring minor differences in type (e.g. int vs. double) (hadley/dplyr#821). Used by all.equal()
for tibbles. (This package contains a pure R implementation of all_equal()
, the dplyr
code has identical behavior but is written in C++ and thus faster.)data_frame()
and as_data_frame()
have been aligned, so as_data_frame()
will now automatically recycle length-1 vectors. Both functions give more informative error messages if you are attempting to create an invalid data frame. You can no longer create a data frame with duplicated names (hadley/dplyr#820). Both functions now check that you don’t have any POSIXlt
columns, and tell you to use POSIXct
if you do (hadley/dplyr#813). data_frame(NULL)
raises error “must be a 1d atomic vector or list”.trunc_mat()
and print.tbl_df()
are considerably faster if you have very wide data frames. They will now also only list the first 100 additional variables not already on screen - control this with the new n_extra
parameter to print()
(hadley/dplyr#1161). The type of list columns is printed correctly (hadley/dplyr#1379). The width
argument is used also for 0-row or 0-column data frames (#18).[.tbl_df()
does not change class (#41, @jennybc). Improve [.tbl_df()
