Dear lists,
   
  Anysuggestion on how to write a loop function which has nx2 matrix as an input, where each of the row represents an interval. the function should return a mx2 matrix containing the no matched interval of x?? i've tried my own function but it's only applies for 2x2 matrix. 
   
  Here is my code:
   
  overlap<-function(x,y){
m=length(x)
n=length(y)
 for(i in 1:m){
  for(j in 1:n){
   if(x[i]>=y[j]) print(TRUE)
   else print(FALSE)
     }
   } 
  }
   
  Many thanks!! 
   
  Cheers,
  Anisah
