R Concatenate Elements

Concatenate Elements

You can also concatenate, or join, two or more elements, by using the paste() function.

To combine both text and a variable, R uses comma (,):

text <- "awesome"

paste("R is", text)

You can also use , to add a variable to another variable:

text1 <- "R is"
text2 <- "awesome"

paste(text1, text2)

For numbers, the + character works as a mathematical operator:

num1 <- 5
num2 <- 10

num1 + num2

If you try to combine a string (text) and a number, R will give you an error:

num <- 5
text <- "Some text"

num + text

Result:

Error in num + text : non-numeric argument to binary operator
