Populate a list with data from another list

Source: R/populate.R

populate copies data from a list (e.g. input by a user) to another list with a similar shape. The second list, called the interface, will generally also contain extra metadata for making API requests, such as names or types.

populate(input, interface)

Arguments

input

A list with data to copy.

interface

A list of a similar shape to copy data into.

Examples

# Make an interface with metadata, e.g. type.
interface <- tag_add(list(foo = c(), bar = c()), list(type = "structure"))

# Combine data and the metadata from the interface.
populate(list(foo = 1, bar = 2), interface)
#> $foo
#> [1] 1
#> 
#> $bar
#> [1] 2
#> 
#> attr(,"tags")
#> attr(,"tags")$type
#> [1] "structure"
#>
