Dear lists,
   
  I'm in my process of learning of writing a function. I tried to write a simple functions of a matrix and a vector. Here are the codes:
   
  mm<-function(m,n){              #matrix function    
 w<-matrix(nrow=m, ncol=n)
 for(i in 1:m){
  for(j in 1:n){
   w[i,j]=i+j
  }
 }
return(w[i,j])
}
   
  v<-function(n){          #function of a vector
 y=vector(length=n)
  for(i in 1:n){
   y[i]=i
  }
 return(y[i])
}
 
  when i tried called on my matrix function; say mm(5,10). what i got is the single value of 15..where's is my matrix?? same thing happened to my vector function. Please help me figure out these problems. Thanks a bunch!!
   
  Cheers, 
  Anisah
