• Moves R/{old}.R to R/{new}.R

• Moves tests/testthat/test-{old}.R to tests/testthat/test-{new}.R

• Moves tests/testthat/test-{old}-*.* to tests/testthat/test-{new}-*.* and updates paths in the test file.

• Removes context() calls from the test file, which are unnecessary (and discouraged) as of testthat v2.1.0.

This is a potentially dangerous operation, so you must be using Git in order to use this function.

## Usage

rename_files(old, new)

## Arguments

old, new

Old and new file names (with or without extensions).
