Annotate R code with inline comments

Description

Annotate R code with inline comments

Usage

annotate_code(code, ...)

Arguments

code

A character vector of R code. If missing the code currently selected in RStudio is documented (If RStudio is used).

...

passed on to askgpt.

Value

A character vector.

Ask openai's GPT models a question

Description

Ask openai's GPT models a question

Usage

askgpt(prompt, chat = TRUE, progress = TRUE, return_answer = FALSE, ...)

Arguments

prompt

What you want to ask

chat

whether to use the chat API (i.e., the same model as ChatGPT) or the completions API.

progress

Show a progress spinner while the request to the API has not been fulfilled.

return_answer

Should the answer be returned as an object instead of printing it to the screen?

...

additional options forwarded to chat_api or completions_api respectively.

Value

either an httr2 response from one of the APIs or a character vector (if return_answer).

Examples

## Not run: 
askgpt("What is an R function?")
askgpt("What is wrong with my last command?")
askgpt("Can you help me with the function aes() from ggplot2?")

## End(Not run)

Request answer from openai's chat API

Description

Request answer from openai's chat API

Usage

chat_api(
  prompt,
  model = NULL,
  config = NULL,
  max_tokens = NULL,
  api_key = NULL,
  ...
)

Arguments

prompt

character string of the prompt to be completed.

model

character string of the model to be used (defaults to "text-davinci-003").

config

a configuration prompt to tell the model how it should behave.

max_tokens

The maximum number of tokens to generate in the completion. 2048L is the maximum the models accept.

api_key

set the API key. If NULL, looks for the env OPENAI_API_KEY.

...

additional parameters to be passed to the API (see [the API documentation](https://platform.openai.com/docs/api-reference/completions)

Value

A tibble with available models

a httr2 response object

Examples

## Not run: 
chat_api("Hi, how are you?", config = "answer as a friendly chat bot")

## End(Not run)

Request answer from openai's completions API

Description

Mostly used under the hood for askgpt.

Usage

completions_api(
  prompt,
  model = NULL,
  temperature = NULL,
  max_tokens = NULL,
  api_key = NULL,
  ...
)

Arguments

prompt

character string of the prompt to be completed.

model

character string of the model to be used (defaults to "text-davinci-003").

temperature

numeric value between 0 and 1 to control the randomness of the output (defaults to 0.2; lower values like 0.2 will make answers more focused and deterministic).

max_tokens

The maximum number of tokens to generate in the completion. 2048L is the maximum the models accept.

api_key

set the API key. If NULL, looks for the env OPENAI_API_KEY.

...

additional parameters to be passed to the API (see [the API documentation](https://platform.openai.com/docs/api-reference/completions)

Details

Only a few parameters are implemented by name. Most can be sent through the .... For example, you could use the n parameter just like this completions_api("The quick brown fox", n = 2).

A couple of defaults are used by the package:

the model used by default is "text-davinci-003"
the default temperature is 0.2
the default for max_tokens is 2048L

You can configure how askgpt makes requests by setting options that start with askgpt_*. For example, to use a different model use options(askgpt_model = "text-curie-001"). It does not matter if the API parameter ist listed in the function or not. All are used.

Value

a httr2 response object

Examples

## Not run: 
completions_api("The quick brown fox")

## End(Not run)

Document R Code

Description

Document R Code

Usage

document_code(code, ...)

Arguments

code

A character vector of R code. If missing the code currently selected in RStudio is documented (If RStudio is used).

...

passed on to askgpt.

Value

A character vector.

Examples

## Not run: 
document_code()

## End(Not run)

Estimate token count

Description

Estimate token count

Usage

estimate_token(x, mult = 1.6)

Arguments

x

character vector

mult

the multiplier used

Details

This function estimates how many tokens the API will make of the input words. For the models 1 word is more than one token. The default multiplier value resulted from testing the API. See <https://help.openai.com/en/articles/4936856-what-are-tokens-and-how-to-count-them> for more information.

Value

a integer vector of token counts

Examples

estimate_token("this is a test")
