data_frame: Build a data frame.

Description

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.

Usage

data_frame(...)
data_frame_(columns)

Arguments

...

A set of named arguments

columns

A lazy_dots.

Examples

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

# data_frame never coerces its inputs
str(data_frame(letters))
str(data_frame(x = diag(5)))

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