Factors: In Data Science we need to deals with huge text data, which is very memory intensive.
hence we need to convert the text into numbers,

 "Factors" encode the strings into number, instead of storing the whole string it store the encoded numbers

Example:

factor_city = factor(c('Delhi' , 'Mumbai' ))

str(factor_city)

Output: 

  Factor w/ 2 levels "Delhi","Mumbai": 1 2
