Matrices in R

Matrices are a special vector in R which holds row and column attributes. It can be created using a vector input to the matrix function.

# Empty

Command::  m <- matrix(1:6, nrow=2, ncol =3)

Print::          print(m)

Output::

[,1] [,2] [,3]

[1,]    1    3    5

[2,]    2    4    6

We can also bind rows /column wise using the command cbind() and rbind()

 x <- 5:7

 y <- 6:8

 rbind(x,y)

  [,1] [,2] [,3]

x    5    6    7

y    6    7    8

 cbind(x,y)

     x y

[1,] 5 6

[2,] 6 7

[3,] 7 8
