Description

rbind a named list of data.frames or vectors to output a single data.frame with the names from the list as an id column.

Usage

tidy_list(
  x,
  id.name = "id",
  content.name = "content",
  content.attribute.name = "attribute",
  ...
)

Arguments

x	A named list of data.frames or vector.
id.name	The name to use for the column created from the list.
content.name	The name to use for the column created from the list of vectors (only used if x is vector).
content.attribute.name	The name to use for the column created from the list of names given to the vectors (only used if x is named vector).
...	Ignored.

Value

Returns a data.table with the names from the list as an id column.

Examples

tidy_list(list(p=1:500, r=letters))
tidy_list(list(p=mtcars, r=mtcars, z=mtcars, d=mtcars))

x <- list(
    a = setNames(c(1:4), LETTERS[1:4]),
    b = setNames(c(7:9), LETTERS[7:9]),
    c = setNames(c(10:15), LETTERS[10:15]),
    d = c(x=4, y=6, 4),
    e = setNames(1:10, sample(state.abb, 10, TRUE)),
    f = setNames(1:10, sample(month.abb, 10, TRUE))
)
