_targets.R

# Created by use_targets().
# Follow the comments below to fill in this target script.
# Then follow the manual to check and run the pipeline:
#   https://books.ropensci.org/targets/walkthrough.html#inspect-the-pipeline

# Load packages required to define the pipeline:
library(targets)

# Set target options:
tar_option_set(
  packages = c("tibble"), # Packages that your targets need for their tasks.
  # format = "qs", # Optionally set the default storage format. qs is fast.
  seed = 123 # Set a seed for reproducibility (needed for data simulation)
)

# Run the R scripts in the R/ folder with your custom functions:
tar_source()
source(here::here("data-raw/algorithm.R"))
source(here::here("data-raw/variable-description.R"))
source(here::here("data-raw/simulate-data.R"))

# Replace the target list below with your own:
