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.
lst()
is similar to list()
, but like tibble()
, it
evaluates its arguments lazily and in order, and automatically adds names.
tibble(...) tibble_(xs) lst(...) lst_(xs)
... |
A set of name-value pairs. Arguments are evaluated sequentially,
so you can refer to previously created variables. These arguments are
processed with |
xs |
A list of unevaluated expressions created with |
as_tibble()
to turn an existing list into
a data frame.
