tibble

Build a data frame or list.

tibble is a trimmed down version of data.frame that:

  1. Never coerces inputs (i.e. strings stay as strings!).
  2. Never adds row.names.
  3. Never munges column names.
  4. Only recycles length 1 inputs.
  5. Evaluates its arguments lazily and in order.
  6. Adds tbl_df class to output.
  7. Automatically adds column names.

Usage
tibble(...)
tibble_(xs)
data_frame(...)
data_frame_(xs)
lst(...)
lst_(xs)
Arguments
...
A set of name-value pairs. Arguments are evaluated sequentially, so you can refer to previously created variables.
xs
A list of unevaluated expressions created with ~, quote(), or lazy.
Details

lst is similar to list, but like tibble, it evaluates its arguments lazily and in order, and automatically adds names.

data_frame is an alias to tibble.

See Also

as_tibble to turn an existing list into a data frame.

Examples
a <- 1:5
tibble(a, b = a * 2)
tibble(a, b = a * 2, c = 1)
tibble(x = runif(10), y = x * 2)

lst(n = 5, x = runif(n))

# tibble never coerces its inputs
str(tibble(letters))
str(tibble(x = list(diag(1), diag(2))))

# or munges column names
tibble(`a + b` = 1:5)

# With the SE version, you give it a list of formulas/expressions
tibble_(list(x = ~1:10, y = quote(x * 2)))

# data frames can only contain 1d atomic vectors and lists
# and can not contain POSIXlt
## Not run: 
# tibble(x = tibble(1, 2, 3))
# tibble(y = strptime("2000/01/01", "%x"))
# ## End(Not run)
