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.

[R] merging two vectors
Hi to all, is there a better way instead for loop to merge two vectors: V1 <- c(1,3,5,7,9) V2<- c(20,40,60,80,100) to V_merged <- c(1,20,3,40,5,60,7,80,9,100) Kind regards Knut __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
