drake (version 5.0.0)

failed: List the targets that failed in the last call to make().

Description

Together, functions failed and diagnose() should eliminate the strict need for ordinary error messages printed to the console.

Usage

failed(path = getwd(), search = TRUE, cache = drake::get_cache(path =
  path, search = search, verbose = verbose), verbose = TRUE)

Arguments

path

Root directory of the drake project, or if search is TRUE, either the project root or a subdirectory of the project.

search

If TRUE, search parent directories to find the nearest drake cache. Otherwise, look in the current working directory only.

cache

optional drake cache. See codenew_cache(). If cache is supplied, the path and search arguments are ignored.

verbose

whether to print console messages

Value

A character vector of target names.

Examples

# NOT RUN {
test_with_dir("Quarantine side effects.", {
load_basic_example() # Get the code with drake_example("basic").
make(my_plan) # Run the project, build the targets.
failed() # Should show that no targets failed.
# Build a workflow plan doomed to fail:
bad_plan <- drake_plan(x = function_doesnt_exist())
try(make(bad_plan), silent = TRUE) # error
failed() # "x"
diagnose(x) # Retrieve the cached error log of x.
})
# }
