# How to Combine Lists in R (With Examples)

You can use either the c() function or the append() function to combine two or more lists in R:

```#combine two lists using c()
combined #combine two lists using append()
combined ```

Both functions will produce the same result.

The following examples show how to use this syntax in practice.

### Example 1: Combine Two Lists

The following code shows how to combine two lists in R:

```#define lists
list1
list2

#combine two lists into one
combined #view combined list
combined

[[1]]
[1] 2

[[2]]
[1] 5

[[3]]
[1] 6

[[4]]
[1] 8

\$A
[1] 1 2 3 4 5

\$B
[1] 3
```

We can also use the length() function to get the length of the combined list:

```#get length of combined list
length(combined)

[1] 6
```

We can also use the class() function to get the class of the combined list:

```#get class of combined list
class(combined)

[1] "list"
```

### Example 2: Combine More Than Two Lists

We can use similar syntax to combine more than two lists in R:

```#define lists
list1
list2

#combine three lists into one
combined #view combined list
combined

[[1]]
[1] 2

[[2]]
[1] 5

[[3]]
[1] 6

[[4]]
[1] 8

\$A
[1] 1 2 3 4 5

\$B
[1] 3

\$X
[1] "A"

\$Y
[1] "B"```
