# How to Split a Vector into Chunks in R

You can use the following basic syntax to split a vector into chunks in R:

```chunks <- split(my_vector, cut(seq_along(my_vector), 4, labels=FALSE))
```

This particular example splits the vector called my_vector into 4 equally sized chunks.

To split the vector into a different number of chunks, simply change the 4 to a different value.

The following example shows how to use this syntax in practice.

## Example: Splitting a Vector into Chunks in R

Suppose we have the following vector in R that contains 12 total elements:

```#create vector
my_vector <- c(2, 2, 4, 7, 6, 8, 9, 8, 8, 12, 5, 4)

#view length of vector
length(my_vector)

 12```

We can use the following syntax to split the vector into four chunks:

```#split vector into four chunks
chunks <- split(my_vector, cut(seq_along(my_vector), 4, labels=FALSE))

#view chunks
chunks

\$`1`
 2 2 4

\$`2`
 7 6 8

\$`3`
 9 8 8

\$`4`
 12  5  4```

From the output we can see:

• The first chunk contains the values 2, 2, 4.
• The second chunk contains the values 7, 6, 8.
• The third chunk contains the values 9, 8, 8.
• The fourth chunk contains the values 12, 5, 4.

Note that we can also use brackets to access a specific chunk:

```#access second chunk only
chunks

\$`2`
 7 6 8
```

If we change the value within the split() function, we can split the vector into a different number of chunks.

For example, we could split the vector into six chunks instead:

```#split vector into six chunks
chunks <- split(my_vector, cut(seq_along(my_vector), 6, labels=FALSE))

#view chunks
chunks

\$`1`
 2 2

\$`2`
 4 7

\$`3`
 6 8

\$`4`
 9

\$`5`
 8 8

\$`6`
 12  5
```

Notice that there are now six chunks and each chunk contains two elements.

Note: If your vector doesn’t contain an even number of elements, this method will still split the vector into as equally-sized groups as possible.
