Explain with example some of the ways of creating a matrix in R.
In R, matrix can be created by many ways
Let us create a matrix in the most simple way
matrix(1:9, nrow = 3, ncol = 3)
Output
In the above matrix, it can be filled row wise by putting byrow=TRUE
Another way of creating a matrix is to bind the rows and columns by using rbind() and cbind() function respectively.
cbind(c(1,2,3),c(4,5,6),c(7,8,9))
Output
[,1] [,2] [,3]
[1,] 1 4 7
[2,] 2 5 8
[3,] 3 6 9
rbind(c(1,2,3),c(4,5,6),c(7,8,9))
[,1] [,2] [,3]
[1,] 1 2 3
[2,] 4 5 6
[3,] 7 8 9
