R programming Unexpected symbol error

Question

I'm new to R programming, I tried this simple function:

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

myfunction()
[1] 0.05248908
dir()
[1] "myfunction.R"
source("myfunction.R")

I get the following error:

Error in source("myfunction.R") : myfunction.R:2:3: unexpected symbol 1: 2: R version

Answer 1

Format your code this way:

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

Let me know if this works.
