In Poush87/foofactors: Make factors less annoying

This is a homework package for stat 547. "foofactors" manipulates factors and makes them easier to deal with. Functions include: fbind to bind two factors together

library(foofactors)
fbind(iris$Species[c(1, 51, 101)], PlantGrowth$group[c(1, 11, 21)])

## [1] setosa     versicolor virginica  ctrl       trt1       trt2      
## Levels: ctrl setosa trt1 trt2 versicolor virginica

freq_out to tabulate a factor

## Source: local data frame [3 x 2]
## 
##            x     n
##       (fctr) (int)
## 1     setosa    50
## 2 versicolor    50
## 3  virginica    50

fctr_or_chr to determine whether input factor should be a factor or character depending on whether distinct levels = observations. Returns TRUE if factor.

levels(iris$Species)

## [1] "setosa"     "versicolor" "virginica"

length(iris$Species)

## [1] 150

#Is the Species variable a factor or not? 
fctr_or_chr(iris$Species)

## [1] TRUE

reorder_factor to reorder the levels in a factor in descending order

levels(iris$Species)

## [1] "setosa"     "versicolor" "virginica"
