I have two sets of interval data.Below are my two dataset. In these dataset, there is a missing values in each of the data. I want to find the non-overlapping interval values. Here is my code:    

  mysetdiff=function(x,y){
  m=length(x)
  n=length(y)
   bx = logical(m)
   by = logical(n)
    for(i in 1:m){

     for(j in 1:n){
      if(x[i]<=y[j]){
        bx[i] = T
        by[j] = T 
      }

    }
  }

     sx = x[!bx]
   sy = y[!by]
 s=c(sx,sy)
return(s)
 }    

  How am i going to remove the NA value in my function?? any sugesstion?? thanks a bunch
