Hi,
Try this:
paste0(expand.grid(a,b)$Var1,expand.grid(a,b)$Var2)
[1] "a1b1" "a2b1" "a1b2" "a2b2"

Dear Ozgur,
Try
sort(apply(expand.grid(a, b), 1, paste0, collapse = ""))

Dear all,
I want to concatenate the elements of two vectors such as
a<-c("a1","a2")
b<-c("b1","b2")
and obtain
"a1b1", "a1b2","a2b1","a2b2"
I tried the paste and paste0 functions, but they yielded elementwise
concatenation such as
"a1b1","a2b2"
I am wondering that is there an efficient way o
If you want to concatenate the *vectors*, you need 'c', which will
also coerce the elements to a common type.
If you want to concatenate the corresponding *elements* of the
vectors, you need 'paste', which will coerce them to character
strings.

Sorry,
I saw the word concatenate and dived in. Andrew Dolmans solution works fine.

Dear users,
a very simple question:
Given two vectors x and y
x<-as.character(c("A","B","C","D","E","F"))
y<-as.factor(c("1","2","3","4","5","6"))
i want to combine them into a single vector z as A1, B2, C3 and so on.
z<-x*y is not working, i tried several others

Something like this should work:
z<- paste(x,y, sep='')

?paste
paste(x,y, sep="")
