How to check if Two Vectors are Equal in R - Step by Step Examples

How to check if Two Vectors are Equal in R ?

To check if two vectors are equal in R, you can use the `identical()` function or the `all.equal()` function.

In this example,

We create two numeric vectors named vector1 and vector2.
We use the identical() function to check if vector1 is identical to vector2.
The identical() function returns TRUE if the vectors are identical, otherwise FALSE.

vector1 <- c(1, 2, 3)
vector2 <- c(1, 2, 3)
identical(vector1, vector2)

[1] TRUE

In this example,

We create two character vectors named vector1 and vector2.
We use the all.equal() function to check if vector1 is equal to vector2.
The all.equal() function returns TRUE if the vectors are equal, otherwise FALSE. It also handles numerical tolerance for numeric vectors.

vector1 <- c('a', 'b', 'c')
vector2 <- c('a', 'b', 'c')
all.equal(vector1, vector2)

[1] TRUE

In this tutorial, we learned How to check if Two Vectors are Equal in R language with well detailed examples.
