Run all code in a file. Changes in data that are tracked, (e.g. with
start_log(data)) will be followed by the assigned loggers.
run_file(file, auto_dump = TRUE, envir = NULL)source_file(file, auto_dump = TRUE)
The environment where the code was executed, invisibly.
[character] file to run.
[logical] Toggle automatically dump all remaining logs
after executing file.
[environment] to run the code in. By default a new environment will be created
with .GlobalEnv as parent.
run\_file runs code in a separate environment, and returns the environment with all
the variables created by the code. source\_file acts like source and
runs all the code in the current global workspace (.GlobalEnv).
