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 .
