# fcuk

A package designed to help people with clumsy fingers.

## Installation of `fcuk`

    if (!require(devtools)){install.packages("devtools")}
    devtools::install_github("ThinkR-open/fcuk")

## Launch and use

After launching this package, every error will be analysed. Each time a typo occurs, a correction suggestion will be made under the default error message.

    library(fcuk)

    # Examples
    sl()
    > Error in sl() : impossible de trouver la fonction "sl"
    Did you mean : ls or nls ?

    iri
    > Erreur : objet 'iri' introuvable
    Did you mean : IQR or iris ?

    view
    > Erreur : objet 'view' introuvable
    Did you mean : View or deriv ?

    mea
    > Erreur : objet 'mea' introuvable
    Did you mean : mean or frame ?

## Stop `fcuk`

You can stop `fcuk` at anytime by calling the `remove_error_tracker` function. Start the error tracker again with `init_error_tracker`.

## Recurrent use of fcuk

You can launch `fcuk` with your R session.

    .First <- function(){
    cat("\n Bonjour !  - ", date(), "\n")
    library(fcuk)
    }

It will be more efficient to add this library to your Rprofile. You can use `fcuk::add_fcuk_to_rprofile()` to do so. Then, any time you launch your R project, `fcuk` will be launched at the same time.

You can also add `fcuk` inside your `Rprofile.site` file. Then you’ll have this functionnality inside all your Rstudio projects.

## fcuk functions

You’ll typically never need to use the functions contained in `fcuk`. You just need to launch this library, and `fcuk` will do his job in the background.

## Feedbacks and questions

Feel free to report any issue you may have with this package.
