Error saying expected symbol in R

Question

myfunction <- function() (  
    x <- rnorm(100)  
    mean(x)   
)

When I attempt to copy this to the console it gives the following error:

Error: unexpected symbol in:
"x <- rnorm(100)
mean"

Then when I type myfunction into the console as instructed I get this:

function() 
x <- rnorm (100)

Answer 1

Write the code in the following way:

myfunction <- function() {  
    x <- rnorm(100)  
    mean(x)   
}
