How to check if Two Lists are Equal in R ?

Answer

To check if two lists are equal in R, you can use the identical function or the all.equal function.

✐ Examples

1 Check Equality Using identical Function

In this example,

We create two lists: list1 and list2 with initial values.
We use the identical function to check if list1 is identical to list2.
Finally, we print the result to standard output.

R Program

list1 <- c(1, 2, 3)
list2 <- c(1, 2, 3)
result <- identical(list1, list2)
print(result)

Output

[1] TRUE

2 Check Equality Using all.equal Function

In this example,

We create two lists: list1 and list2 with initial values.
We use the all.equal function to check if list1 is equal to list2.
Finally, we print the result to standard output.

R Program

list1 <- c(1, 2, 3)
list2 <- c(1, 2, 3)
result <- all.equal(list1, list2)
print(is.na(result))

Output

[1] TRUE
