'''Tibbles''' are a re-engineered [[R/DataFrames|data frame]]. They are available from the '''`tibble`''' package.

== Installation ==

The `tibble` package is commonly used through [[R/Tidyverse|Tidyverse]].

== Usage ==

A tibble is instantiated like:

{{{
> t1 <- tibble(foo = c(1,2,4),
               bar = c("a","b","c"),
               constant10 = 10)

> t2 <- as_tibble(data.frame(foo = c(1,2,4),
                             bar = c("a","b","c"))

> t3 <- as_tibble(matrix(1:9, nrow=3))

> t4 <- as_tibble(matrix(1:9, nrow=3), .name_repair="universal")

> t5 <- as_tibble(matrix(1:9, nrow=3), rownames="casenum", .name_repair="universal")
}}}

In comparison to [[R/DataFrames|data frames]]:
 * Input column vectors ''must'' either be the same length, or be a scalar value. Only scalars are recycled.
 * `t3` here has column names like V1 and so on. But a warning is issued; see `t4` for the officially supported method.
 * Tibbles do not store row names. This is mostly relevant when casting a matrix, as data frames usually use an ID column for row names. `t5` here shows how to retain the row names as a new column.

Note that tibbles store each column separately, and that tibbles instantiate the columns sequentially. It is possible to declare a column as a function of prior columns.

Tibbles are [[R/DataTypes#Classes|multiclassed]] as both `data.frame` and `tbl_df`.
