completions4R: Generate text using OpenAI completions API (Legacy - DEPRECATED)

Description

**[WARNING] DEPRECATED AND SCHEDULED FOR REMOVAL**: This function uses the legacy OpenAI completions API which is being phased out by OpenAI. **This function will be removed in a future version.**

**MIGRATION REQUIRED**: Please migrate to chat4R() for all new implementations. The chat4R() function uses the modern OpenAI Chat Completions API and provides better performance, more features, and continued support.

**Migration Example**: “'r # Old (deprecated): result <- completions4R("Your prompt here")

# New (recommended): result <- chat4R("Your prompt here") text_content <- result$content “'

This function sends a request to the OpenAI completions API to generate text based on the provided prompt and parameters.

Usage

completions4R(
  prompt,
  api_key = Sys.getenv("OPENAI_API_KEY"),
  Model = "gpt-3.5-turbo-instruct",
  max_tokens = 50,
  temperature = 1,
  simple = TRUE
)

Arguments

prompt	A string. The initial text that the model responds to.
api_key	A string. The API key for OpenAI. Defaults to the value of the environment variable "OPENAI_API_KEY".
Model	A string. The model ID to use, such as "davinci-002" or "gpt-3.5-turbo-instruct".
max_tokens	Integer. The maximum number of tokens to generate.
temperature	A numeric value to control the randomness of the generated text. A value close to 0 produces more deterministic output, while a higher value (up to 2) produces more random output.
simple	If TRUE, returns the generated text without newline characters. If FALSE, returns the full response from the API.

Value

The generated text or the full response from the API, depending on the value of 'simple'.
