argh

The goal of {argh} is to (try) to provide advice on obscure R error messages.

Disclaimer and notes

• The messages returned by {argh} try to explain what the error is. There is no guarantee they succeed.

• So far, there are 10 errors analyzed for English.

• So far it works with English, French and Korean. But feel free to contribute with your translation of inst/en_errors.csv.

• Also, please note that this package will override any other error handler running, until you call stop_argh() (but I’m working on that).

Installation

You can install the dev version of {argh} with:

remotes::install_github("ColinFay/argh")

Launch {argh}

library(argh)
init_argh()

Wait for an error to occur:

> iri
Error: object 'iri' not found
argh...
The object you are looking for might not exist. 
> library(dpylr)
Error in library(dpylr) : there is no package called ‘dpylr’
argh...
You might have forgotten to install a package or have mispelled the package name 
> "a" + "b"
Error in "a" + "b" : non-numeric argument to binary operator
argh...
You might have tried to use a character vector where a numeric is needed. 
> mean$Sepal.Length
Error in mean$Sepal.Length : object of type 'closure' is not subsettable
argh...
You might have called `$` on a function.
...

Stop {argh}

stop_argh()

Contribute

You can contribute by:

• adding examples into the inst/en_errors.csv csv of errors. On each line, the first element is a regex that catches the error, the other is a message (trying) to explain the error.

• add a translation of inst/en_errors.csv.
