Description

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.

Usage

run_file(file, auto_dump = TRUE, envir = NULL)
source_file(file, auto_dump = TRUE)

Value

The environment where the code was executed, invisibly.

Arguments

file

[character] file to run.

auto_dump

[logical] Toggle automatically dump all remaining logs after executing file.

envir

[environment] to run the code in. By default a new environment will be created with .GlobalEnv as parent.

Details

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).
