Read a target from a tarflowr project and return its value.

A simple wrapper around targets::tar_read(). This function reads the value of a target from a completed or running tarflowr pipeline and returns it as an object. This is generally preferred over tarflowr_load() for programmatic access.

Usage

tarflowr_read(name, project_dir)

Arguments

name

The unquoted name of the target to read.

project_dir

The path to the tarflowr project directory.

Value

The value of the target.

Examples

if (FALSE) { # \dontrun{

td <- file.path(tempdir(), "_my_project")

tarflowr_run(
  work_units = list(a = 1, b = 2),
  process_func = function(x) x * 10,
  combine_func = function(x) sum(unlist(x)),
  project_dir = td
)

# inspect the processed work units
punits <- tarflowr_read(processed_unit, project_dir = td)
punits

# inspect the final result
res <- tarflowr_read(my_project_result, project_dir = td)
res
} # }
