How do you concatenate strings in R?

To concatenate strings in r programming, use paste() function. The syntax of paste() function that is used to concatenate two or more strings.

Concatenating strings in R is less than intuitive. You don’t use a . operator, nor a + operator, and forget about the & operator. In fact, you don’t use an operator at all. Concatenating strings in R requires the use of the paste() function. Here’s an example:

hello <- "Hello, " world <- "World." paste(hello, world) [1] "Hello, World."

I’ve stored Hello, and World. in variables aptly named hello and world. With paste(), I’ve simply plugged in the two variables, and it concatenates them such that it creates the single phrase “Hello, World.”

An oddity with this function is that it will automatically insert spaces between the terms. Try it out with some numbers.

paste(1,2,3,4) [1] "1 2 3 4"

This can be a sort of “gotcha” with this question. If we don’t want spaces, we can adjust the sep parameter in the function, which defaults to a space " ".

paste(1,2,3,4,sep=“”) [1] "1234"
