Retrieve Docker tags for a Rocker image — .get_r_ver

Queries the Docker Hub API to retrieve all available tags for a specified Rocker image. Supports user-friendly modes: "base", "tidyverse", "rstudio", "verse", "shiny_server", and "rstudio_shiny". Returns a structured list containing the image name, tag vector, and source URL.

Usage

.get_r_ver_tags(r_mode = "base", verbose = FALSE)

Arguments

r_mode: Character string. One of "base", "tidyverse", "rstudio", "verse", "shiny_server", or "rstudio_shiny". Determines which Rocker image to query. "base" maps to "rocker/r-ver". "rstudio_shiny" maps to "rocker/rstudio", since it's built by layering Shiny Server onto that image rather than a separate Docker Hub repository.
verbose: Logical. If TRUE, prints progress messages during tag retrieval and pagination. Defaults to FALSE.

Value

A named list with three elements: image (the full Docker image name), tags (character vector of all available tags), and source (the base URL of the Docker Hub API).
