Performing different Operations on Two Arrays in R Programming – outer() Function
outer() function in R Language is used to apply a function to two arrays.
Syntax: outer(x, y, FUN=”*”, …)
Parameters:
x, y: arrays
FUN: function to use on the outer products, default value is multiply
Example 1:
Python3
# R program to illustrate# outer function# Initializing two arrays of elementsx <- c(1, 2, 3, 4, 5)y<- c(2, 4, 6)# Multiplying array x elements with array y elements# Here multiply (*) parameter is not used still this# function take it as defaultouter(x, y) |
Output:
[, 1] [, 2] [, 3] [1, ] 2 4 6 [2, ] 4 8 12 [3, ] 6 12 18 [4, ] 8 16 24 [5, ] 10 20 30
Example 2:
Python3
# R program to illustrate# outer function# Initializing two arrays of elementsx <- c(1, 2, 3, 4, 5)y<- c(2, 4, 6)# Adding array x elements with array y elementsouter(x, y, "+") |
Output:
[, 1] [, 2] [, 3] [1, ] 3 5 7 [2, ] 4 6 8 [3, ] 5 7 9 [4, ] 6 8 10 [5, ] 7 9 11
