Hi Desmond,
You might try
> sort(apply(expand.grid(v1, v2), 1, paste, collapse = "", sep = ""))
[1] "a1" "a2" "a3" &qu
x<-letters[1:3]
y<-1:3
d<-expand.grid(x,y)
g<-apply(d,1,function(x) paste(x[1],x[2],sep=""))

Hi Desmond,

[1] "a1" "a2" "a3" "b1" "b2" "b3"

Dear R-help readers,
I'm sure this problem has been answered but I can't find the solution.
I have two vectors
v1 <- c("a","b")
v2 <- c(1,2,3)
I want an easy way to produce every possible combination of v1, v2 elements
Ie I want to produce
c("a1","a2","a3", "b1","b2","b3")
regards
Desmond
