# c() Function in R (2 Examples)

This article illustrates how to combine values into a vector or list using the c() function in R.

The content looks as follows:

Hereâ€™s the step-by-step processâ€¦

## Definition & Basic R Syntax of c Function

Definition: The c R function combines multiple values into a vector or list.

Basic R Syntax: You can find the basic R programming syntax of the c function below.

`c(value1, value2)                # Basic R syntax of c function`

In the following, Iâ€™ll show you two examples for the application of the c function in the R programming language.

## Example 1: Combine Numeric Values in Vector Using c() Function

In Example 1, Iâ€™ll explain how to use the c function to create a new vector object that contains several numeric values.

For this, we simply have to specify all values we want to add to our new vector within the c function. We have to separate these values by a comma:

`x1 <- c(1, 5, 3, 8, 8, 6)        # Applying c() function`

Letâ€™s have a look at the data object x1 that we have just created:

```x1                               # Print output
# 1 5 3 8 8 6```

As you can see in the RStudio console, our new vector consists of the numeric values we have specified within the c function.

## Example 2: Combine Variable & Numeric Values

Example 2 explains how to concatenate an already existing vector object with new values. For this example, weâ€™ll use the vector object created in Example 1. We can append new values to this vector as shown in the following R code:

`x2 <- c(x1, 5, 7, 1)             # Concatenate variable & values`

The final output consists of the input vector x1 and the new elements that we have specified within the c command:

```x2                               # Print output
# 1 5 3 8 8 6 5 7 1```
