How to concatenate two strings in R

In this tutorial, we are going to learn about concatenating two strings in the r programming language.

String concatenation means joining the two strings into a single string.

Concatenating two strings

We can concatenate the two strings into a single string by using the paste() function in R language.

Here is an example:

x <- "hello"
y <- "world"
result = paste(x, y) # joining
print(result)

Output:

[1] "hello world"

You can also concatenate two strings by using a separator (-) like this:

x <- "hello"
y <- "world"
result = paste(x, y, sep= "-")
print(result)

Output:

[1] "hello-world"

Similarly, you can also use the stri_paste() function from the stringi package.

library(stringi)

first = 'josh'
last = 'wa'
name = stri_paste(first,last) # joining
print(name)

Output:

[1] "joshwa"

The stri_paste() function also accepts separator as an thrid argument.

name = stri_paste(first,last,sep='-') # josh-wa
