You can use one of the following methods in R to concatenate a vector of strings together:

**Method 1: Use paste() in Base R**

paste(vector_of_strings, collapse=' ')

**Method 2: Use stri_paste() from stringi Package**

library(stringi) stri_paste(vector_of_strings, collapse=' ')

Both methods will produce the same result but the **stri_paste()** method will be faster, especially if you’re working with extremely large vectors.

The following examples show how to use each method in practice.

**Example 1: Concatenate Vector of Strings Using paste() in Base R**

The following code shows how to concatenate together a vector of strings using the **paste()** function from base R:

#create vector of strings vector_of_strings <- c('This', 'is', 'a', 'vector', 'of', 'strings') #concatenate strings paste(vector_of_strings, collapse=' ') [1] "This is a vector of strings"

Note that the **collapse** argument specifies the delimiter to place in between each string.

In the example above, we used a space. However, we could use any delimiter we’d like such as a dash:

#create vector of strings vector_of_strings <- c('This', 'is', 'a', 'vector', 'of', 'strings') #concatenate strings using dash as delimiter paste(vector_of_strings, collapse='-') [1] "This-is-a-vector-of-strings"

We can even use no delimiter if we’d like each of the strings to be concatenated with no spaces in between:

#create vector of strings vector_of_strings <- c('This', 'is', 'a', 'vector', 'of', 'strings') #concatenate strings using no delimiter paste(vector_of_strings, collapse='') [1] "Thisisavectorofstrings"

**Example 2: ****Concatenate Vector of Strings Using str_paste() from stringi Package**

The following code shows how to concatenate together a vector of strings using the **stri_paste()** function from the **stringi** package in R:

library(stringi) #create vector of strings vector_of_strings <- c('This', 'is', 'a', 'vector', 'of', 'strings') #concatenate strings stri_paste(vector_of_strings, collapse=' ') [1] "This is a vector of strings"

Notice that this produces the same result as the **paste()** function from base R.

The only difference is that this method will be faster.

Depending on the size of the string vectors you’re working with, the difference in speed may or may not matter to you.
