Hi Nicoletta,

You need to read more introductory material.

One of the problems with your code is that you actually don't create any

value, let alone any vector; you just display it with cat().

Then you try to create each value of your vector with an explicit for

loop, but you don't need to; replicate() does the job in a compact code.

So if I understand correctly what you want to achieve, I would do this:

kolmo <- function(x, meanR=0, sdR=1, repet=1){

out <- replicate(repet, mean(rnorm(x, meanR, sdR)))

return(out)

}

# I changed the names of your arguments to make it less confusing (but I

wasn't imaginative)

# I set some default values for 'meanR' and 'sdR', which are actually

the defaults of rnorm()

# 'return(out)' is not necessary but I prefer to explicitly write what I

want the function to output

Example:

kolmo(x=10, repet=3)

HTH,

Ivan

> I need a function, that calculates the mean of a desired amount of normally distributed numbers and repeats this process for a desired number of repetitions. The function should return only a single vector consisting solely of the calculated means. Also the user of this function must be able to specify the parameters of the normal distribution used while calculating the means. I need this function for the Kolmogorov Smirnov Test.
