Ambiguous Whether `btw("{pkg}")` Returns Both Vignette/reference Or Just One

Introduction

The btw function in R is a powerful tool for displaying package information, including vignettes and function references. However, there appears to be an ambiguity in the behavior of btw("{pkg}"), which returns either the introductory vignette or the function reference, depending on the package's availability. In this article, we will delve into the current implementation of btw and explore the implications of this behavior.

Current Implementation of btw

According to the source code of btw, the function returns the introductory vignette if it's available, otherwise it returns the function reference. This behavior is documented in the help page of btw.

# R/btw_this.R
if (vignette_exists(pkg, "intro")) {
  # Return introductory vignette
  return(vignette(pkg, "intro"))
} else {
  # Return function reference
  return(reference(pkg))
}

README Documentation

However, the README of the btw package indicates that the function would return both the introductory vignette and the function reference.

# README.Rmd
btw("{pkg}") returns both the introductory vignette and the function reference.

Implications of Ambiguous Behavior

The current implementation of btw has several implications:

• In the case where a package has an intro vignette, there's no way to retrieve the full function reference with btw.
• The full function reference is super nice to include in a system prompt so that the model can tool call for a specific help page for a package without first having to tool call for the full reference.

Advocating for a Change in Behavior

Based on the implications of the current implementation, I would personally advocate for the function returning both the introductory vignette and the function reference, as described in the README.

Benefits of Returning Both

Returning both the introductory vignette and the function reference would provide several benefits:

• Users would have access to both types of information, making it easier to understand the package and its functions.
• The full function reference would be available, allowing users to tool call for a specific help page for a package without first having to tool call for the full reference.
• The behavior of btw would be more consistent with the README documentation.

Conclusion

In conclusion, the behavior of btw("{pkg}") is ambiguous, returning either the introductory vignette or the function reference, depending on the package's availability. I advocate for a change in behavior, returning both the introductory vignette and the function reference, as described in the README. This would provide several benefits, including access to both types of information and a more consistent behavior with the README documentation.

Recommendations

Based on the analysis of the current implementation and the implications of the ambiguous behavior, I recommend the following:

• Update the source code of btw to return both the introductory vignette and the function reference.
• Update the help page of btw to reflect the new behavior.
• Update the README documentation to reflect the new behavior.
