# Combine Two or Multiple Vectors in R

To append two or more vectors into a single list or combine multiple vectors in R, you can use either the combine function c() or append() function. In this article, I will explain examples of using these two methods to combine multiple vectors in R.

Let’s create the three character vectors to use, I will define them as `vec1`, `vec2`, and `vec3`.

``````
# Create vectors to append
vec1 = c('sai','ram','deepika','sahithi')
vec2 = c('kumar','scott','Don','Lin')
vec3 = c('Ram','Denis')
``````

## 1. R Combine Two Vectors using c()

By using combine function c() you can append two vectors into a single vector in R. This function takes two vectors as an argument and returns the combined vector. The following example combines the elements from `vec1` and `vec2` objects into a single vector `vec4`.

Here c() is a combined function from the base package that can be used to combine lists, vectors, and other objects. These base functions are default available with the R installation and automatically loaded to the program.

``````
# combine two vectors
vec4 <- c(vec1,vec2)
print(vec4)
``````

Yields below output.

## 2. Combine Two Vectors using append()

Alternatively, you can also use append() to get two vectors into a single vector in R. This function also takes two vectors as an argument and returns the combined vector.

``````
# combine two vectors
vec4 <- append(vec1,vec2)
print(vec4)
``````

Yields the same output as above.

## 3. Combine Multiple Vectors using append()

Finally by using the append() let’s combine multiple vectors into a single vector in R. The below examples combine elements from `vec1`, `vec2` and `vec3` into a single vector `vec4`.

``````
# combine multiple vectors
vec4 <- c(vec1,vec2,vec3)
print(vec4)

vec4 <- append(vec1,vec2,vec3)
print(vec4)
``````

Yields below output.

## 4. Complete Example

Following is a complete example of appending two or multiple vectors.

``````
# create vectors
vec1 = c('sai','ram','deepika','sahithi')
vec2 = c('kumar','scott','Don','Lin')
vec3 = c('Ram','Denis')

# combine two vectors
vec4 <- c(vec1,vec2)
print(vec4)

# combine two vectors
vec4 <- append(vec1,vec2)
print(vec4)

# combine multiple vectors
vec4 <- c(vec1,vec2,vec3)
print(vec4)

vec4 <- append(vec1,vec2,vec3)
print(vec4)
``````

## 5. Conclusion

In this article, you have learned how to append two vectors into a single vector using the R c() combine function and append() function from R base package.
