fuzzybunnies

fuzzybunnies contains a function called df_apply() that applies any function to a data frame. It expects a data frame, a function, and another function that filters which columns of the data frame you want to apply the given function to.

Installation

You can install the development version of fuzzybunnies from GitHub with:

# install.packages("devtools")
devtools::install_github("treytipton4/fuzzybunnies")

Example

This is a basic example which shows you how to apply the floor() function to the numeric columns of a data frame using df_apply():

library(fuzzybunnies)

head(xyz_fuzzybunnies)
#>     x y     z
#> 1 1.1 4 Hello
#> 2 2.5 5    Hi
#> 3 3.9 6   Hey

This example applies an existing R command, floor(), to the xyz dataframe - again only applying it to the numeric columns. The floor function rounds all numbers down to the nearest integer, thus, when using the df_apply(), the y and z columns should remain the same while the x column is changed to the values 1, 2, and 3. Let’s watch it work

new_xyz <- df_apply(xyz_fuzzybunnies, floor, is.numeric)

head(new_xyz)
#>   x y     z
#> 1 1 4 Hello
#> 2 2 5    Hi
#> 3 3 6   Hey
