Q:

r find elements in common between vectors

# Basic syntax:
intersect(vector_1, vector_2) # For two vectors
Reduce(intersect, list(vector_1, vector_2, vector_3)) # For multiple vectors

# Example usage:
vector_1 = c(1,2,3,4,5)
vector_1 = c(2,4,6,8)
intersect(vector_1, vector_2)
--> 2 4

# Note, the vectors don't have to have the same length
1
# setdiff gives the the difference of the 1st compared to the second. 
setdiff(b,a)
