Example
            Enter the following code snippet:

                r <- c(‘orange’,’mango’,16,FALSE)
                print(r)
                p <- c(1:7,10.5,’NEXT’)
                print(p)
            The following result is produced:
















            6.7.3 accessing Vector elements

            There are several methods of accessing  vector elements:
                a.  using position
                b.  using logical indexing
                c.  using negative indexing

                d.  using 0/1 indexing
            a.  using position
            You can access the data using the position of each data element in the sequence. Here the position numbering starts
            with 1.
            Example
            Enter the following code snippet:


                # Accessing vector elements using position
                t <- c("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul")
                u <- t[c(1,3,6)]
                print(u)
            Observe here the types of brackets in the third line of the above program snippet.
            The following result is produced:
