list2df: List to data.frame

In mark: Miscellaneous, Analytic R Kernels

List to data.frame

Description

Converts a list object into a data.frame

Usage

list2df(x, name = "name", value = "value", show_NA, warn = TRUE)

Arguments

x	A (preferably) named list with any number of values
name, value	Names of the new key and value columns, respectively
show_NA	Ignored; if set will trigger a warning
warn	Logical; if TRUE will show a warning when

Details

Unlike base::list2DF(), list2df() tries to format the data.frame by using the names of the list as values rather than variables. This creates a longer form list that may be more tidy.

Value

a data.frame object with columns "name" and "value" for the names of the list and the values in each

Examples

x <- list(a = 1, b = 2:4, c = letters[10:20], "unnamed", "unnamed2")
list2df(x, "col1", "col2", warn = FALSE)

if (getRversion() >= as.package_version('4.0')) {
# contrast with `base::list2DF()` and `base::as.data.frame()`
  x <- list(a = 1:3, b = 2:4, c = letters[10:12])
  list2df(x, warn = FALSE)
  list2DF(x)
  as.data.frame(x)
}
