Question 1

How to handle custom data types when parsing YAML in R?

Accepted Answer

Use the custom handlers feature in the yaml package by defining handlers for specific YAML tags to control conversion to R objects. Refer to the vignette('yaml') for examples on advanced usage and formatting options.

Question 2

yaml package vs jsonlite for reading configuration files in R?

Accepted Answer

The yaml package is optimized for YAML files with libyaml's fast parsing, while jsonlite excels with JSON. Choose yaml for YAML-specific needs like configuration files, but if your data is JSON, jsonlite might offer better integration and performance for that format.

Question 3

How to install yaml package if libyaml is missing on my system?

Accepted Answer

Install from CRAN typically handles dependencies, but if libyaml is not available, you may need to install it via system package managers like apt-get or Homebrew. Check your OS documentation or the package's system requirements for guidance.

Question 4

What's the difference between yaml.load and read_yaml?

Accepted Answer

yaml.load() parses a YAML string directly into an R object, while read_yaml() reads from a file path. Both functions convert YAML to R, but read_yaml is more convenient for file-based operations, as shown in the README examples.

Question 5

Does the yaml package support YAML 1.2 specifications?

Accepted Answer

Yes, since it binds to libyaml, which aims to support YAML 1.2. However, for edge cases or specific features, test with your YAML data or consult libyaml's documentation to ensure full compatibility.

Question 6

How to write nested lists to YAML using as.yaml?

Accepted Answer

Pass the nested list directly to as.yaml(), and it will recursively convert it to YAML format. Use parameters like indent to control output structure, as demonstrated in the README with the list example for better readability.
