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 ?

unique(c(x,y))
