Variables in R can be different types and we
need to distinguish numbers from character strings and tables from simple lists
of numbers .To distinguish numbers from characters we always use quotes("") for characters. The function class() helps us determine the type of an object .

Introduction
This is my first
post on R programming. In this series of posts , we will cover the building
blocks of R I.e different data types used , Vectors ,Operations on these
vectors like Vector Arithmetic, Sorting , indexing , plots , programming basics
of R i.e using the conditional operators , for loops , functions etc. I will
not be covering installation since there are various existing detailed sources
available .
