In acastroaraujo/bizarro: This packages transforms inputs into "bizarro outputs"

BIZARRO

• This toy packages transforms inputs into “bizarro outputs”.

• It was created as an exercise for the Building Tidy Tools workshop at RStudio Conference 2020.

• It contains a single generic function bizarro(), powered by the R’s S3 object-oriented system.

Installation

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("acastroaraujo/bizarro")

Example

This is a basic example which shows you how to solve a common problem:

library(bizarro)

bizarro("andrés castro araújo")
#< [1] "ojúara ortsac sérdna"

## works on lists
example <- list(numeric = 1:10, 
                factor = factor(stringr::fruit[1:5]),
                logical = c(TRUE, FALSE, NA, FALSE, TRUE)
                )

bizarro(example)
#< $numeric
#<  [1]  -1  -2  -3  -4  -5  -6  -7  -8  -9 -10
#< 
#< $factor
#< [1] elppa       tocirpa     odacova     ananab      reppep lleb
#< Levels: reppep lleb ananab odacova tocirpa elppa
#< 
#< $logical
#< [1] FALSE  TRUE    NA  TRUE FALSE

## works on data frames (and nested data frames)
bizarro(iris)
#< # A tibble: 150 x 5
#<    Sepal.Length Sepal.Width Petal.Length Petal.Width Species
#<           <dbl>       <dbl>        <dbl>       <dbl> <fct>  
#<  1         -5.1        -3.5         -1.4        -0.2 asotes 
#<  2         -4.9        -3           -1.4        -0.2 asotes

#<  9         -4.4        -2.9         -1.4        -0.2 asotes 
#< 10         -4.9        -3.1         -1.5        -0.1 asotes 
#< # … with 140 more rows

## doesn't work on dates
bizarro(as.Date("1990-04-03"))
#< Error: Don't know how to make bizzaro <Date>
