In eachanjohnson/errR: Graceful error handling for R

errR

errR is a minimal framework which wraps R's tryCatch into a system of binary operators to make defensive programming more succinct and readable.

Installation

Not yet on CRAN. Install using devtools:

devtools::install_github('eachanjohnson/errR')

Usage

Currently supports two related idioms:

<code that might produce an error> %except% <recovery code>

<code that might produce an error> %except% <function to handle error message>

In an interactive R session, try:

stop('This is an error!')

Then compare with:

stop('This is an error!') %except% print('Error, but continuing anyway')

See how this compares to:

stop('This is an error!') %except% print

To do

• Handle warnings
• Add %finally% operator
