today I want to make post about usage of factor in R.
So, first of all, what is factor at all?
I was surprised to see that factor is very overloaded term and can have a lot of meanings in many areas. So, for what factors can be used in R?
First of all they can be used for storing categorical or nominal values. For example it can be convenient for saving gender, blood group, car type, etc.
So, let's say you wrote something like this:
cars.classes <- c("Coupe", "Cabriolet", "Sport", "Hatchback")
For now cars.classes is not a factor, but just character vector.
If you execute this code in RStudio, and then execute in RStudio following line:
cars.classes … more
