Matrix <- bind vectors

Often, you won't be creating vectors like we did in the last example. Instead, you will create them from multiple vectors that you want to combine together. For this, it is easiest to use the functions cbind() and rbind() (column bind and row bind respectively). To see these in action, let's combine two vectors of Apple and IBM stock prices:

apple <- c(109.49, 109.90, 109.11, 109.95, 111.03)
ibm <- c(159.82, 160.02, 159.84, 160.35, 164.79)

cbind(apple, ibm)

      apple    ibm
[1,] 109.49 159.82
[2,] 109.90 160.02
[3,] 109.11 159.84
[4,] 109.95 160.35
[5,] 111.03 164.79

rbind(apple, ibm)

        [,1]   [,2]   [,3]   [,4]   [,5]
apple 109.49 109.90 109.11 109.95 111.03
ibm   159.82 160.02 159.84 160.35 164.79

Now its your turn!
