Title:	Run Multiple Large Language Model Predictions Against a Table, or Vectors
Description:	Run multiple 'Large Language Model' predictions against a table. The predictions run row-wise over a specified column. It works using a one-shot prompt, along with the current row's content. The prompt that is used will depend of the type of analysis needed.

Categorize data as one of options given

Description

Use a Large Language Model (LLM) to classify the provided text as one of the options provided via the labels argument.

Usage

llm_classify(
  .data,
  col,
  labels,
  pred_name = ".classify",
  additional_prompt = ""
)

llm_vec_classify(x, labels, additional_prompt = "", preview = FALSE)
llm_classify(
  .data,
  col,
  labels,
  pred_name = ".classify",
  additional_prompt = ""
)

llm_vec_classify(x, labels, additional_prompt = "", preview = FALSE)

Arguments

`.data`	A `data.frame` or `tbl` object that contains the text to be analyzed
`col`	The name of the field to analyze, supports `tidy-eval`
`labels`	A character vector with at least 2 labels to classify the text as
`pred_name`	A character vector with the name of the new column where the prediction will be placed
`additional_prompt`	Inserts this text into the prompt sent to the LLM
`x`	A vector that contains the text to be analyzed
`preview`	It returns the R call that would have been used to run the prediction. It only returns the first record in `x`. Defaults to `FALSE` Applies to vector function only.

Value

llm_classify returns a data.frame or tbl object. llm_vec_classify returns a vector that is the same length as x.

Examples


library(mall)

data("reviews")

llm_use("ollama", "llama3.2", seed = 100, .silent = TRUE)

Specify the model to use

Description

Allows us to specify the back-end provider, model to use during the current R session

Usage

llm_use(

  model = NULL,
  ...,
  .silent = FALSE,
  .cache = NULL,
  .force = FALSE
)
llm_use(
  backend = NULL,
  model = NULL,
  ...,
  .silent = FALSE,
  .cache = NULL,

Arguments

`backend`	The name of an supported back-end provider. Currently only 'ollama' is supported.
`model`	The name of model supported by the back-end provider
`...`	Additional arguments that this function will pass down to the integrating function. In the case of Ollama, it will pass those arguments to `ollamar::chat()`.
`.silent`	Avoids console output
`.cache`	The path to save model results, so they can be re-used if the same operation is ran again. To turn off, set this argument to an empty character: `""`. It defaults to a temp folder. If this argument is left `NULL` when calling this function, no changes to the path will be made.
`.force`	Flag that tell the function to reset all of the settings in the R session

Value
