To understand and create a matrix in R, read this shot.
The cbind()
function adds additional columns to a matrix in R.
cbind(matrix, c(column elements))
The cbind()
function takes two parameter values:
matrix
: This is the existing matrix to which we will add a column.column elements
: This is the list of elements we wish to add to the new column.The cbind()
function returns a modified matrix with a new column.
# creating a matrixmyMatrix <- matrix(c("apple", "banana", "cherry", "orange","grape", "pineapple", "pear", "melon", "fig"), nrow = 3, ncol = 3)# adding a colum using the cbind() functionmyNewMatrix <- cbind(myMatrix, c("lemon", "mango", "strawberry"))# printing the new matridmyNewMatrix
3
by 3
matrix (a matrix with 3 rows and 3 columns) myMatrix
using the matrix()
function. We then passing the parameter values of its shape. nrow = 3
represents 3 rows, and ncol = 3
represents 3 columns.cbind()
function to add a new column of elements to the existing matrix.myNewMatrix
.It is worth noting that the new column must be the same length as the current matrix.
