R help - Sep 2003 - What is wrong with m?

I've been programming in one directory and recently switched to another 
directory.  It appears that in doing so I've uncovered a problem.  My 
environment was saving something so that my code would work and now I don't 
know how to fix it.  I have the following bit of code:

  for(i in 1:index){
    indexList = lst[i]
	for(j in 2:jobs-1){
           indexList = c(indexList,lst[i+index*j])
        }
   saveList[i,] = indexList

   }


   for (i in 1:index){
	m[i] = median(saveList[i,])

}
m

In my new directory, I am getting the complaint that "object m is not
found."
Does anyone know what that means?

For "m[1] <- ..." to work, "m" must already be defined. 
To fix this,
execute "m <- rep(NA, index)" before your second "for"
loop, and it
should work. 

hope this helps.
