Hello,

I'm posting this again (with some small edits). I didn't get any replies
last time...hoping for some this time. :)

Currently I'm only coming up with brute force solutions to this issue
(loops). I'm wondering if anyone has a better way to do this. Thank you for
your help in advance!

The problem: I have endpoints of one x range (x_rng) and an unknown number
of s ranges (s[#]_rng) also defined by the range endpoints. I'd like to
remove the x ranges that overlap with the s ranges. The examples below
demonstrate what I mean.

What is the best way to do this?

Ex 1.
For:
x_rng = c(-100,100)

s1_rng = c(-25.5,30)
s2_rng = c(0.77,10)
s3_rng = c(25,35)
s4_rng = c(70,80.3)
s5_rng = c(90,95)

I would get:
-100,-25.5
35,70
80.3,90
95,100

Ex 2.
For:
x_rng = c(-50.5,100)

s1_rng = c(-75.3,30)

I would get:
30,100

Ex 3.
For:
x_rng = c(-75.3,30)

s1_rng = c(-50.5,100)

I would get:
-75.3,-50.5

Ex 4.
For:
x_rng = c(-100,100)

s1_rng = c(-105,105)

I would get something like:
NA,NA
or...
NA

Ex 5.
For:
x_rng = c(-100,100)

s1_rng = c(-100,100)

I would get something like:
-100,-100
100,100
or just...
-100
 100

PS - You may have noticed that in all of the examples I am including the s
range endpoints in the desired results, which I can deal with later in my
program so its not a problem...  I think leaving in the s range endpoints
simplifies the problem.

Thanks!
Ben
