Create a YAML-style list from a named vector or list

This function takes a named vector or list and converts it into a YAML-style list of key–value pairs. Each element is represented as `- key: value`. If a file path is provided, the YAML output is written to disk.

Usage

create_yml(x, file = NULL)

Arguments

x

A named vector or list. The names will be used as keys, and the corresponding values as values. `NA` values are converted to empty strings.

file

Optional. A character string giving the path to a file where the YAML output should be written. If `NULL` (default), the result is returned instead of written.

Value

If `file` is `NULL`, returns a character vector with one entry per YAML item. If `file` is not `NULL`, the YAML output is written to the specified file and the result is returned invisibly.

Examples

# Create a simple YAML list from a named vector
x <- c(name = "Alice", age = 30, country = NA)
create_yml(x)
#> [1] "- name: Alice\n  age: 30\n  country: \n  "
