Description

Hi

I have a targets pipeline with dynamic branching, and a final target which combines all targets from the branch. I would like now to have a report (quarto document) which is based on a branch.

Essentially I have (the last two targets):

tar_target(
    group_output,
    list(
      name = paste0("IPBES_", group$name, "_", group$id),
      zotero_group = zotero_group,
      bibliography = bibliography,
      metrics = metrics,
      pub_year_data = figure_pub_year_data,
      pub_year = figure_pub_year,
      oa_status_data = figure_oa_status_data,
      oa_status = figure_oa_status,
      top_journals_data = figure_top_journals_data,
      top_journals = figure_top_journals,
      types_data = figure_types_data,
      types = figure_types
    ),
    pattern = map(
      group,
      zotero_group,
      bibliography,
      metrics,
      figure_pub_year_data,
      figure_pub_year,
      figure_oa_status_data,
      figure_oa_status,
      figure_top_journals_data,
      figure_top_journals,
      figure_types_data,
      figure_types
    ),
    iteration = "list"
  ),

  # Create Bibliograpy Report ----------------------------------------------
  tarchetypes::tar_render(
    group_report,
    path = "bibliography_Report.qmd",
    params = list(results = group_output),
    # output_file = paste0(branch_output$name, ".html"),
    pattern = map(group_output), <=== HERE IS THE PROBLEM
    iteration = "vector",
    format = "file"
  ),

Well - this is what I would like to have - but pattern is not an argument from tar_render (it will be forwarded to the render commend, if I am not mistaken).

My Question: How can I render a quarto report per dynamic branch? Do I have to use tar_target() and a rendering function?

Thanks.

Just to add to it:

I am now using

    group_report,
    {
      out_dir <- file.path("output", "report", "bibliography")
      out_file <- paste0(group_output$name, ".html")

      quarto::quarto_render(
        input = "bibliography_Report.qmd",
        execute_params = list(output_files = group_output),
        output_file = out_file
      )

      dir.create(
        dirname(out_dir),
        recursive = TRUE,
        showWarnings = FALSE
      )
      to_file <- file.path(out_dir, basename(out_file))

      file.rename(
        out_file,
        to_file
      ) # move out_file
      to_file
    },
    pattern = map(group_output),
    format = "file"
  ),

which works, but does not track the quarto file (I could add a file target for that - I know).

You're on the right track. You could track the Quarto file by returning c(to_file, "bibliography_Report.qmd").

Thanks. That or defining it as an input file (downstream dependency).Correct?On 23 May 2025, at 20:49, Will Landau ***@***.***> wrote: You're on the right track.
