# How to Append Values to List in R (With Examples)

You can use the following syntax to append a single value to a list in R:

```#get length of list called my_list
len <- length(my_list)

#append value of 12 to end of list
my_list[[len+1]] <- 12
```

And you can use the following syntax to append multiple values to a list in R:

```#get length of list called my_list
len <- length(my_list)

#define values to append to list
new <- c(3, 5, 12, 14)

#append values to list
i = 1
while(i <= length(new)) {
my_list[[i+len]] <- new[i]
i <- i + 1
}```

The following examples show how to use each of these functions in practice.

### Example 1: Append a Single Value to a List

Suppose we have the following list in R:

```#create list
my_list <- list(7, 14, c(1, 2, 3))

#view list
my_list

[]
 7

[]
 14

[]
 1 2 3
```

We can use the following syntax to append the value 12 to the end of the list:

```#get length of list
len <- length(my_list)

#append value to end of list
my_list[[len+1]] <- 12

#view list
my_list

[]
 7

[]
 14

[]
 1 2 3

[]
 12
```

### Example 2: Append Multiple Values to a List

Suppose we have the following list in R:

```#create list
my_list <- list(7, 14, c(1, 2, 3))

#view list
my_list

[]
 7

[]
 14

[]
 1 2 3
```

We can use the following syntax to append several values to the end of the list:

```#get length of list
len <- length(my_list)

#define values to append to list
new <- c(3, 5, 12, 14)

#append values to list
i = 1
while(i <= length(new)) {
my_list[[i+len]] <- new[i]
i <- i + 1
}

#display updated list
my_list

[]
 7

[]
 14

[]
 1 2 3

[]
 3

[]
 5

[]
 12

[]
 14
```
