Unused argument in R

I am calling two function repeatedly (Nrep times) and save the results using the below code:

repeat.gendat <- function(Nreps,N, quantilelist=c(0,1,5,50,95,99,100),
                          distrib='norm',n.mean=5, n.stdev=3,e.lambda=0.1,
                          qq=0.5,M=1) {
  for (j in 1:Nreps) {
    if (j==1) {
      if (distrib=='norm') { output.data <- gen.norm.dat(N,n.mean,n.stdev,quantilelist)}
      if (distrib=='exp')  { output.data <- gen.exp.dat(N,e.lambda,quantilelist)}
      if (distrib=='binom')  { output.data <- 
        gen.binom.dat(N,qq, M,quantilelist)}
    }
    if (j>1) {
      if (distrib=='norm') { output.data <- rbind(output.data,
                                 gen.norm.dat(N,n.mean,n.stdev,quantilelist)) }
      if (distrib=='exp') { output.data <- rbind(output.data,
                                 gen.exp.dat(N,e.lambda,quantilelist)) }
      if (distrib=='binom') { output.data <- rbind(output.data,
                                 gen.binom.dat(N,qq,M,quantilelist)) }
      }
  } 
return(output.data)
}

And then to generate the normally distributed data I run the below code in Rstudio:

data1 <- repeat.gendat(100, 50,quantilelist=c(0,1,5,50,95,99,100),
                       distrib='norm', n.mean = 5, n.stdev = 3)

But I am getting this error: Error in rnorm(Nreps, N, n.mean, n.stdev) : unused argument (n.stdev) I don't know where I am wrong. Any help would be appreciated

Paria, please use "code sample" option to indicate your code lines.

Is the function gen.norm.dat from a library, or did you define it elsewhere? This function is likely calling rnorm incorrectly, but I wouldn't be able to help without knowing the origin of the function.

The parameters for rnorm is rnorm(N, mean, sd). I guess what you are trying to do here is to generate multiple normally distributed values. For that you will need to do replicate(Nreps, rnorm(N, n.mean, n.stdev)) in the gen.norm.dat function.

The problem was solved. That is right I did not run gen.norm.data before this code. Thank you all

How did you resolve the problem?

The gen.norm.data was a function and without defining it I was trying to run it. So, that was the reason I was getting the error. I run the gen.norm.data function. Does that make sense?
