In RobbyLankford/foofactors: Make Factors Less Annoying

NOTE: This is a toy package, do not actually use it

foofactors

Factors are a very useful type of variable in R, but they can also be very aggravating. This package provides some helper functions for the care and feeding of factors.

Installation

# install.packages("devtools")
devtools::install_github("RobbyLankford/foofactors")

Example

Binding two factors via ‘fbind()’:

library(foofactors)
a <- factor(c("character", "hits", "your", "eyeballs"))
b <- factor(c("but", "integer", "where it", "counts"))

Simply catenating two factors leads to a result that most don’t expect.

c(a, b)
#> [1] 1 3 4 2 1 3 4 2

The ‘fbind()’ function glues to factors together and returns a factor.

fbind(a, b)
#> [1] character hits      your      eyeballs  but       integer   where it 
#> [8] counts   
#> Levels: but character counts eyeballs hits integer where it your

Often we want a table of frequencies for the levels of a factor. The ‘fcount()’ function returns a frequency table as a tibble.

set.seed(1234)
x <- factor(sample(letters[1:5], size = 100, replace = TRUE))
freq_out(x)
#> # A tibble: 5 x 2
#>   x         n
#>   <fct> <int>
#> 1 a        19
#> 2 b        19
#> 3 c        21
#> 4 d        22
#> 5 e        19
