combinations of the elements of two vectors
Hi
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

Hi Desmond,
You might try
sort(apply(expand.grid(v1, v2), 1, paste, collapse = , sep = ))
[1] a1 a2 a3 b1 b2 b3

I have two
x-letters[1:3]
y-1:3
d-expand.grid(x,y)
g-apply(d,1,function(x) paste(x[1],x[2],sep=))
