Mean on random numbers

General
1

Hello,

I'm beggining on R and i'm trying to create a function which gives me a vector of randow numbers.

For that, i do like this :

The problem is that i want to make a print of the mean and the standard deviation of thoses random numbers but i can't do it.

Thank you for your help.

If I've understood your problem this chunk of code will satisfy:

Random <- function (x)
{
  Vector<-c(rnorm(x))
  paste("The mean is",mean(Vector),"and the standard deviation is:",sd(Vector),".")
}

Random(10)

Thanks for your answer.

But in fact, the work i have to do must follow 2 steps :

    1. To generate a vector of random numbers
    1. To use "print" to give the mean and the standard deviation of those random numbers of step 1.

You mean something like this?

Random <- function (x)
{
  Vector<-c(rnorm(x))
  writeLines("The generated vector is:")
  print(Vector)
  writeLines(paste0("The mean is ",mean(Vector),", and the standard deviation is ",sd(Vector),"."))
}

Random(10)

That is exactly the result i wanted, thank you very much for your help
