In jeffbone/First-Package: Makes Factors Less Annoying

Overview

This package is designed to simplify working with factors. It consists of three functions as outlined below.

Package Installation

One must first install and load the package.

#install.packages("FirstPackage")
devtools::install_github("jeffbone/First-Package")

Data to be Used in Examples

fruit <- c("Apples","Oranges","Bananas")
fruit <- as.factor(fruit)
gourd <- c("Potatoes","Yams","Squash")
gourd <- as.factor(gourd)
veg <- c("Carrots","Bell Peppers","Celery")
veg <- as.factor(veg)

Example of fbind

fbind takes two factors and puts them together into one. The input is two factors and the output is one factor. For example,

#example 1
fbind(fruit,gourd)

#example 2
fbind(veg,fruit)

#example 3
fbind(1,2) #won't run if inputs are not factors

Example of freq_out

freq_out creates a frequency table for a factor. The input must be a factor and the output is a tbl data frame. For example,

#example 1
fruit_sample <- sample(fruit,20,rep=TRUE)
fruit_sample
freq_out(fruit_sample)

#example 2
veg_sample <- sample(veg,20,rep=TRUE)
combined_fruit_veg <- fbind(fruit_sample,veg_sample)
freq_out(combined_fruit_veg)

#example 3
freq_out(c(1,1,1,1)) #won't run if input is not a factor

Example of reorder_factor

reorder_factor reorders the levels of a factor based on frequency. The input is a factor and the output is the same factor with reordered levels. For example,

#example 1
veg_sample <- sample(veg,20,rep=TRUE)
veg_sample
reorder_factor(veg_sample)

#example 2
reorder_factor(gourd) #doesn't reorder if all levels have same number

#example 3
reorder_factor(c(1,2,3)) #doesn't run if input is not a factor
