I have these vectors with character: the main features are that they have diffferent length. My original vectors a much bigger than these:
a<-c("a","b","c","E","L")
b<-c("E","L","f","b","q","u")
c<-c("a","E","b","L")
d<-c("b","a","a","E","g","h","L")
How do I implement a routine that makes it find all the letters that belongs to all the vectors on the same time:
The final output should be :
final<-c("E","L")
