Tibbles are a modern take on data frames. They keep the features that have stood the test of time, and drop the features that used to be convenient but are now frustrating.



tibble() is a nice way to create data frames. It encapsulates best practices for data frames:


To complement tibble(), tibble provides as_tibble() to coerce objects into tibbles. Generally, as_tibble() methods are much simpler than as.data.frame() methods. The method for lists has been written with an eye for performance:

l <- replicate(26, sample(100), simplify = FALSE)
names(l) <- letters

timing <- bench::mark(
  check = FALSE


The speed of as.data.frame() is not usually a bottleneck when used interactively, but can be a problem when combining thousands of messy inputs into one tidy data frame.

Tibbles vs data frames

There are three key differences between tibbles and data frames: printing, subsetting, and recycling rules.


When you print a tibble, it only shows the first ten rows and all the columns that fit on one screen. It also prints an abbreviated description of the column type, and uses font styles and color for highlighting:

tibble(x = -5:100, y = 123.456 * (3^x))

Numbers are displayed with three significant figures by default, and a trailing dot that indicates the existence of a fractional component.

You can control the default appearance with options:

See ?pillar::pillar_options and ?tibble_options for the available options, vignette("types") for an overview of the type abbreviations, vignette("numbers") for details on the formatting of numbers, and vignette("digits") for a comparison with data frame printing.


Tibbles are quite strict about subsetting. [ always returns another tibble. Contrast this with a data frame: sometimes [ returns a data frame and sometimes it just returns a vector:

df1 <- data.frame(x = 1:3, y = 3:1)
class(df1[, 1:2])
class(df1[, 1])

df2 <- tibble(x = 1:3, y = 3:1)
class(df2[, 1:2])
class(df2[, 1])

To extract a single column use [[ or $:


Tibbles are also stricter with $. Tibbles never do partial matching, and will throw a warning and return NULL if the column does not exist:

df <- data.frame(abc = 1)

df2 <- tibble(abc = 1)

However, tibbles respect the drop argument if it is provided:

data.frame(a = 1:3)[, "a", drop = TRUE]
tibble(a = 1:3)[, "a", drop = TRUE]

Tibbles do not support row names. They are removed when converting to a tibble or when subsetting:

df <- data.frame(a = 1:3, row.names = letters[1:3])

tbl <- tibble(a = 1:3)
rownames(tbl) <- letters[1:3]
rownames(tbl[1, ])

See vignette("invariants") for a detailed comparison between tibbles and data frames.


When constructing a tibble, only values of length 1 are recycled. The first column with length different to one determines the number of rows in the tibble, conflicts lead to an error:

tibble(a = 1, b = 1:3)
tibble(a = 1:3, b = 1)
tibble(a = 1:3, c = 1:2)

This also extends to tibbles with zero rows, which is sometimes important for programming:

tibble(a = 1, b = integer())
tibble(a = integer(), b = 1)

Arithmetic operations

Unlike data frames, tibbles don't support arithmetic operations on all columns. The result is silently coerced to a data frame. Do not rely on this behavior, it may become an error in a forthcoming version.

tbl <- tibble(a = 1:3, b = 4:6)
tbl * 2
