Generate a targets Pipeline from a climasus4r RAP — sus_rap

Converts a rap_object or a pipeline expression into a ready-to-use _targets.R file. The generated script uses targets::tar_target() with optional dynamic branching over UFs, years, or their Cartesian product.

Usage

sus_rap_targets(
  pipeline,
  file_path = "_targets.R",
  branching = c("none", "uf", "year", "cross"),
  workers = 1L,
  include_qc = TRUE,
  lang = "pt",
  overwrite = FALSE
)

Arguments

pipeline: A rap_object (from sus_rap_read()) or a quoted pipeline expression (from quote()).
file_path: character(1) - Output path. Default "_targets.R".
branching: character(1) - Branching strategy: "none" (default), "uf", "year", or "cross".
workers: integer(1) - Number of parallel workers. Default 1.
include_qc: logical(1) - Add a quality-control target. Default TRUE.
lang: character(1) - Language for messages.
overwrite: logical(1) - Overwrite existing file. Default FALSE.

Value

Invisibly, the path of the generated _targets.R file.

Branching strategies

"none": Single analysis, no branching.
"uf": One branch per UF - ideal for multi-state comparisons.
"year": One branch per year.
"cross": All UF-year combinations via tidyr::crossing().

Examples

if (FALSE) { # \dontrun{
rap <- sus_rap_read("pipeline_sp.R")
sus_rap_targets(rap, "_targets.R", branching = "uf", workers = 4)
# then run: targets::tar_make()
} # }
