Dear R users,
 
It may be very simple but it is being difficult for me.
I have two vectors with some common string. And, i want to combine into a vector in such a way that it includes string from both vectors and make a unique.
 
For example: 
 
x <- paste(rep("A",5),1:5,sep = ".")
x
[1] "A.1" "A.2" "A.3" "A.4" "A.5"

y <- paste(rep("A"),3:7, sep = ".")
y
[1] "A.3" "A.4" "A.5" "A.6" "A.7"

Now, I want to combine these two vectors in the following way:
 
"A.1" "A.2" "A.3" "A.4" "A.5"  "A.6" "A.7"
 
I tried with merge(), but not able to get as I want.
 
Is there any way to do this in R ?
 
If it is, it will be great.
Thanks in advance.
 
Regards,
Ram Kumar Basnet.
