| tibble {tibble} | R Documentation |
tibble() is a trimmed down version of data.frame() that:
Never coerces inputs (i.e. strings stay as strings!).
Never adds row.names.
Never munges column names.
Only recycles length 1 inputs.
Evaluates its arguments lazily and in order.
Adds tbl_df class to output.
Automatically adds column names.
data_frame() is an alias to tibble().
tibble_() and its alias data_frame_() use lazy evaluation and are
deprecated. New code should use tibble() or data_frame() with
quasiquotation.
lst() is similar to list(), but like tibble(), it
evaluates its arguments lazily and in order, and automatically adds names.
lst_() uses lazy evaluation and is deprecated. New code should use lst()
with quasiquotation.
tibble(...) data_frame(...) lst(...)
... |
A set of name-value pairs. Arguments are evaluated sequentially,
so you can refer to previously created variables. These arguments are
processed with |
as_tibble() to turn an existing list into
a data frame.
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)
# You can splice-unquote a list of quotes and formulas
tibble(!!! list(x = rlang::quo(1:10), y = quote(x * 2)))
# data frames can only contain 1d atomic vectors and lists
# and can not contain POSIXlt
