Help-Rs,
I've got three vectors representing participants:
vec1 <-
c(4,5,6,7,8,9,10,11,12,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81)
vec2 <- c
(1,2,3,4,5,6,7,8,9,10,11,12,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66)
vec3 <- c (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,52)
I'd like to return a vector that contains only the values that are shared
across ALL THREE vectors. So the statement would return a vector that looked
like this:
4,5,6,7,8,9,10,11,12,52
For some reason I initially thought that a cbind and a unique() would handle
it, but then common sense sunk in. I think the sleep deprivation is starting
to take it's toll. I've got to believe that there is a simple solution to this
dilema.
Thanks in adance for any help!
