# How to Convert Data Frame Column to List in R

You can use the following methods to convert a data frame column to a list in R:

Method 1: Convert One Column to List

```my_list <- list(df\$my_column)
```

Method 2: Convert All Columns to Lists

`all_lists <- as.list(df)`

The following examples show how to use each method in practice with the following data frame in R:

```#create data frame
df <- data.frame(team=c('A', 'B', 'C', 'D', 'E'),
points=c(99, 90, 86, 88, 95),
assists=c(33, 28, 31, 39, 34),
rebounds=c(30, 28, 24, 24, 28))

#view data frame
df

team points assists rebounds
1    A     99      33       30
2    B     90      28       28
3    C     86      31       24
4    D     88      39       24
5    E     95      34       28```

## Example 1: Convert One Data Frame Column to List in R

We can use the following code to convert the points column in the data frame to a list:

```#convert points column to list
points_list <- list(df\$points)

#view list
points_list

[[1]]
[1] 99 90 86 88 95```

The new variable called points_list represents the points column in the data frame as a list.

We can use the class() function to confirm that points_list is indeed a list:

```#display class of points_list
class(points_list)

[1] "list"```

## Example 2: Convert All Data Frame Columns to Lists in R

We can use the following code to convert each column in the data frame to a list:

```#convert all columns to lists
all_columns_list <- as.list(df)

#view lists
all_columns_list

\$team
[1] "A" "B" "C" "D" "E"

\$points
[1] 99 90 86 88 95

\$assists
[1] 33 28 31 39 34

\$rebounds
[1] 30 28 24 24 28
```

We can also use brackets [ ] to extract a specific column as a list:

```#view first column as list
all_columns_list[1]

\$team
[1] "A" "B" "C" "D" "E"```

The output displays the first column in the data frame (“team”) as a list.
