i am probably just missing this one, but how can i check to see if a number
is a part of a vector?

i know i could do a loop checking for equivalence for each element, but i am
thinking that there must be a simpler way to do it than that ( i think that
i have even done it in the past, but can't remember how!)
thanks

what i am working with:
(hope this makes sense)

arclist
  [1]   2   2   6   7   8   9   9  11  11  11  12  13  14  15  16  17  19
21
 [19]  22  23  24  25  25  29  29  30  32  34  35  35  38  39  40  40  41

 [37]  43  44  45  46  47  48  49  50  51  52  53  54  57  58  59  60  61

94
[109]  95  96  96  96  96 100

# and am sampling from a different list
# if i draw, say 80, i would then not want to proceed, but if i draw a
number on arclist i do
