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 (,):
Example
python
text <- "awesome"
paste("R is", text)
You can also use , to add a variable to another variable:
Example
python
text1 <- "R is"
text2 <- "awesome"
paste(text1,
text2)
For numbers, the + character works as a mathematical operator:
Example
python
num1 <- 5
num2 <- 10
num1 + num2
If you try to combine a string (text) and a number, R will give you an error:
Example
python
num <- 5
text <- "Some text"
num + text
Result:
Error in num + text : non-numeric argument to binary operator
