Data Structure - Factor
What is a Factor?
✍: FYIcenter.com
A factor is a data structure that stores a vector and its distinct values as categories.
1. Create a factor object with the factor() function -
> f = factor( c("Bike", "Car", "Truck", "Car", "Bike", "Truck") ) > f [1] Bike Car Truck Car Bike Truck Levels: Bike Car Truck > typeof(f) [1] "integer" > is.factor(f) [1] TRUE
2. Get factor length and members -
> f = factor( c("Bike", "Car", "Truck", "Car", "Bike", "Truck") ) > length(f) [1] 6 > f[4] [1] Car Levels: Bike Car Truck
